Bleeding Profile / Time / Screen / Studies

Bleeding Times are no longer performed by WDP. If the word bleeding appears on the request please contact Coagulation at Myaree or the Haematologist to verify what tests are to be performed.

Blood Culture

Principles

Blood cultures are taken to detect if bacteria is present in the patient’s blood stream. Care must be taken to avoid contamination of the sample with bacteria from other sources, eg the patient’s skin or the hands of the blood collector. Key Points for the BioMerieux BacT/Alert blood culture system:

Always inoculate the blood culture bottles FIRST i.e . before distributing the blood into other specimen containers. If multiple tests have been requested, the blood culture bottles must be filled first,

Each set of blood culture bottles requires an aerobic (green top) AND an anaerobic (orange top) bottle.

Multiple blood culture sets may be taken from the same site all at once, unless specified by the requestor. If unsure, contact the Duty Microbiologist for advice.

Inoculated blood culture bottles must be kept at room temperature until they can be sent to the Laboratory.

Paediatric / Neonate Bleeds- Must be placed into the BacT/Alert Yellow Paediatric Blood Culture Bottle.

Difficult collects (low volume) -The BacT/Alert Yellow Paediatric Blood Culture Bottle is recommended for difficult child or adult bleeds.

Check the expiry date of the blood culture bottles before specimen collection.

Bottles showing cloudiness, contamination, seepage or discoloration must not be used.

If an additional set of blood cultures is required, then perform the entire procedure again.

If you require clarification contact your Supervisor or the Duty Microbiologist.

Urea Breath Test On CHILDREN

These are the instructions from TriMed in getting children to perform the BT when they can't swallow the capsule: 1. Check to see if child can breathe into and inflate the balloon - if they can't do this, no point in doing test. 2. Child must either brush teeth with toothpaste or rinse out mouth with medicated mouth

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 12 of 74

rinse (e.g Listerine) prior to swallowing contents of capsule - this can be done while step 5 below is being performed by collecting staff. This also means that we need to consider supplying collecting centers with mouth rinse for this purpose. 3. Pour 30mL sterile saline into plastic cup 4. Pull BT capsule apart, allow beads to fall into sterile saline in cup 5. Shake for 2-3 mins until beads have visibly dissolved - this is when child should be having mouth rinsed or cleaned. 6 Resulting mixture should look cloudy & green and there may be some settling of material at bottom = starch & sugar within capsule 7. Then get child to drink the mixture 8. After this, follow standard procedure as if child has swallowed capsule.

Coagulation Protocols

Refer to Coagulation Table on following page for number of tubes to collect. If you calculate that you will collect more than 5 citrate tubes - ring Myaree Coagulation 9317 0999. We can probably reduce the number required! Any other queries, please ring. Please note tests marked as $ will incur out of pocket expense to the patient. Check Billing brochure for more details – patient must be informed.

Transport of Samples to Laboratory

1. Platelet function, platelet aggregation, PFA-100, PFA-200:

Freshness of the sample is essential for these tests. These tests must be transported at room temperature – do not put on cool packs or ice bricks.

Platelet Aggregation must be received within 1 hour of collection, and must be collected before 1pm Monday – Friday only. Very specialised test - must ring Myaree Coagulation for permission to proceed.

PFA-100, PFA-200 must be received within 4 hours of collection.

Platelet function can mean either PFA or Platelet Aggregation – must ring Myaree Coagulation to clarify as they have different requirements.

If after acceptable hours or time requirement can not be met, (eg after 1pm for Platelet Aggregation), arrange an alternative collection time or place so that stipulated time frames can be met.

Alternatively, arrange for urgent transportation to the Myaree lab.

2. Samples for routine coag only (Coag profile including PT, APTT, Fibrinogen, TCT):

Send in to Myaree, UNSPUN, at room temperature in blue bag, same day.

If samples will be received at Myaree after 9 pm, they should be placed UNSPUN in a red bag to ensure they are processed same day.

Regional centres in WA: citrates in RED bag, marked urgent.

3. Samples for special coag +/- routine coag tests above (vWF screen, Factors, Thrombophilia, Lupus Anticoagulant, etc):

Send in to Myaree, UNSPUN, at room temperature in blue bag within 10 hours.

If citrates will not reach Myaree within 10 hours, arrange an alternative collection time or place so that stipulated time frames can be met.

Alternatively, the citrates may be spun, separated, and plasma frozen (see WI-COLL-40) at -15°C or colder, then transported on dry ice. “Bar Fridges” and/or Frozen Transport Containers must not be used for coagulation samples.

Collection of Samples 1. Complete the Coagulation Questionnaire (FRM-COLL-43/P1). Remember to Lab

Number this form & fax it as well as the request form. 2. If for thrombophilia testing, prothrombin gene, APCR or FV Leiden also complete

the Genetics Tests Questionnaire (FRM-COLL-31/P34). Remember to Lab Number this form & fax it as well as the request form.

3. If there are multiple tube types follow the correct order of draw (specifically, citrates first).

4. Once collected, transport citrates & any other sample types to the lab as per the current procedure. Remember - platelet function/aggregation studies must be kept at room temperature. All other non-separated citrates should be stored in the fridge until the courier arrives.

5. For frozen samples follow WI-COLL-40 and call lab manager to log the frozen when dispatched on dry ice with the courier.

Disaccharides.

Freezing ASAP is required. Wrap container in foil and send to Lab ASAP on dry ice. This is a Doctor collect only. Always contact Duty Manager first.

Donovanosis

Donovanosis is most reliably diagnosed by Histological examination of a pinch biopsy of the lesion. If this is not possible, a thick smear can be submitted but, while a positive result is helpful, a negative result does not exclude the diagnosis. Collection of the smear is as follows: 1. Fully expose the lesion and clean all debris and surface material from an

ulcerated area. 2. When the base is exposed and raw it is vigorously scraped with a scalpel,

even if this induces some bleeding. 3. The scrapings are put onto a glass slide so that a distinct opaque area 2 x

1.5cms is apparent to the naked eye. 4. The smear is air dried. Fix the smear for 3 minutes in methanol. If methanol

not available, dispatch unfixed. 5. The patient’s name is written on the opaque end of the slide.

Ear Swab

Ear swabs may be indicated for two reasons. Otitis Media - Usually the patient will be a child with a history of ear ache. The pain may have been relieved when there was a discharge from the ear. This occurs because the pus from the middle ear has seeped through the ear drum. The specimen should be collected within 48 hours. 1. Clean away any obvious gunk with a saline moistened swab. 2. Take a second sterile swab. 3. Pull the pinna (ear) upwards and backwards (this straightens the ear canal). 4. Gently push the swab into the ear until all the cotton wool bud is in. 5. Rotate through 360 degrees. 6. Withdraw and let go of the pinna. 7. Make a smear on a new glass slide. 8. Place swab into transport media. Otitis Externa - This is inflammation of the ear canal.

1. Clean away any obvious gunk with a saline moistened swab. 2. Take a second sterile swab. 3. Pull the pinna (ear) upwards and backwards (this straightens the ear canal). 4. If you can see reddened skin, sample this area, otherwise - 5. Gently push the swab into the ear until all the cotton wool bud is in. 6. Rotate through 360 degrees. 7. Withdraw and let go of the pinna. 8. Make a smear on a new glass slide. 9. Place swab into transport media. NB: The organisms causing the inflammation will be on the skin surface of the canal. The

organisms growing in the debris may not be relevant.

6. Transport to laboratory frozen. * Separated samples MUST be labelled with: Full name DOB Lab No. Date and time of collection Type of specimen (eg. SST, EDTA)

Eye Swab

Conjunctivitis can be caused by bacteria, chlamydia or viruses. Bacterial infections often cause the lids to become sticky and there may be a purulent discharge. Chlamydia infections can cause a sticky eye, which in long standing cases may lead to scarring of the eyelids and eventually to inversion of the eyelids and blindness-trachoma. Viral conjunctivitis usually produces reddened eyes with only a slight discharge, although the eyes may be sticky and gritty. NB: all forms of conjunctivitis can be very infectious. Always remove your gloves and

wash your hands after collecting the specimens. Wash and dry your gloved hands thoroughly between collecting each swab if you may have contaminated them.

Procedure 1. Eye or conjunctival swab for MC&S 2. Pull down the lower lid and take of any pus with the swab (Blue top). Smear the swab

onto the centre of a labelled glass slide. Take a second swab from the everted conjunctiva and then place into a tube of ‘the Transport Swab’. If there is no pus then gently but firmly rub the swab along the inside of the lower lid, from nose to ear, once.

3. Repeat the procedure (if necessary) on the other eye, using completely fresh swabs. 4. Dry swabs for viral PCR are collected similarly and stored at room temperature. 5. Chlamydia swabs are taken by first cleaning away any discharge that may be present,

using a Dacron swab. Then, using an APTIMA swab, swab the lower and then the upper conjunctiva 2-3 times each. Use a separate swab for each eye. Swab the least affected eye first to reduce “customer resistance”.

6. Replace the swab in its transport tube. 7. A dry swab (orange/black top tubes) may be used if APTIMA swab not available. Scrapings for eosinophilia: This test may be requested when allergic conjunctivitis is suspected. The lower eyelid should be everted while the reverse (blunt) end of a sterile scalpel blade is used to gently, evenly but firmly scrape across the conjunctiva. The scalpel blade may be safely held in its foil wrapper, with the sharp point and blade covered. The scrapings are then smeared on one or two labelled glass slides and immediately fixed in 95% ethanol.

Faeces Micro, Culture & Sensitivity / Faeces Multiplex PCR

The detection of pathogenic micro-organisms is most likely to be increased if multiple faeces are collected. If the request is for multiple faeces for M, C & S, then collect two samples, the second being seven days after the first on a separate request form. The patient must be instructed to present the samples when collected and not to store the first waiting for the second. If there is an overnight delay in dispatch of these samples, then store them in the fridge in a biohazard bag.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 22 of 74

GIVE THE PATIENT A COPY OF FORM P14 (Faecal specimen collection information sheet). Multiplex PCR (panel FPM) for the detection of the most common enteric bacteria and parasites can be performed when request forms request ‘MCS + PCR’. This assay is only to compliment the MC&S and parasite microscopy and not to be used as a replacement. Normal collection procedures should be exercised 1x Faeces

Faecal Occult Blood (FOB)

FOB rapid testing is used to screen for lower gasterointestinal diseases, such as colorectal cancers and large adenomas that bleed. Testing is usually performed on 3 specimens to increase the sensitivity of the testing process, as cancers can bleed intermittently, and blood may not be uniformly distributed in faecal samples. If the request is for multiple samples, they need to be collected on separate days (daily is fine). The patient should be instructed to return the samples as they are collected. Alternatively, they may be kept in the fridge (2-8degC) for up to 72 hours. GIVE THE PATIENT A COPY OF FORM P33 (FRM-COLL-30) and the correct number of brown top specimen containers with biohazard bags.

Faeces for Parasites (O, C & P)

The detection of pathogenic enteric parasites is most likely to be increased if multiple faeces are collected. If the request is for multiple faeces for parasites, then collect two samples two to four days apart. If a third was requested then collect this sample seven days after the first on a separate request form. The patient must be instructed to present the samples when collected and not to store the first waiting for the second. If there is an overnight delay in dispatch of these samples, then store them in the fridge in a biohazard bag. GIVE THE PATENT A COPY OF FORM P14 (Faecal specimen collection information sheet for brown top containers). If the request is for fixed samples for parasites, then these special containers with SAF fixative inside, will need to be obtained from stores. GIVE THE PATIENT A COPY OF FORM P28 (Faecal specimen collection information sheet for brown and SAF, aqua blue top, containers that will be issued with the SAF containers).

Gentamicin/ Tobramycin

Aminoglycosides are toxic. Toxicity is mainly directed at the ear and the kidney. A number of factors influence the incidence of toxicity and these must be considered when using these drugs. The strongest association for ototoxicity is with age. The combined effect of elevated trough levels and prolonged therapy is also an important risk factor for ototoxicity. Detection and correction of elevated trough levels is an important way of preventing nephrotoxicity.

Procedure The requesting doctor must clearly state the nature of the drug treatment regime being used (Conventional, Once daily dose or Modified once daily dosing). Check with the doctor to clarify. If serum creatinine is not indicated on request form and the requesting doctor is present, ask the doctor if he wishes to request creatinine also (have him indicate this on the request form). This creatinine level can be taken on either peak or trough level collections. Note on request form:

time, date and amount of last dose

route - IV or IM

age, height, weight and gender of patient.

Conventional Dosing

1. Collect TROUGH and PEAK levels

Once a Day Dosing

1. Collect 1 x CLOT 6 - 12 hours AFTER the dose.

(NOTE: This is neither a PEAK nor a TROUGH)

Modified Once a Day Dosing

Herpes simplex Virus (HSV)/Varicella Zoster Virus (VZV)

PCR test should be done on all patients with lesions. Immunofluorescence is not available. Principle Herpes simplex virus is responsible for “cold sores” (usually HSV type 1) and genital herpes (usually HSV type 2). Infected skin cells obtained by scraping of the parabasal and basal layers (the floor of a blister) of a herpes lesion may be done by PCR. Varicella zoster virus is the virus which causes chicken pox (Varicella) and shingles (Herpes zoster). PCR for identification of this virus should be obtained in the same way as for Herpes simplex virus tests.

Materials 1. Sterile surgical scalpel blade # 15 (Swann Morton) 2. Sterile cotton tipped wooden swab stick. 3. Cleaning alcohol swabs 4. Gloves Note: Items 1,2, 3 & 4 are included in the “Herpes kit”

Procedure PCR for Herpes simplex and Varicella Zoster viruses 1. If there is free pus or exudate on the lesions, remove with a cleaning swab without disturbing

the base of the lesion(s) 2. Expose the base of the lesion(s) by lifting the top of a vesicle (blister), pustule or scab with the

cutting edge of the scalpel blade 3. If pus or fluid is present in the de-roofed lesion swab with the cotton swab, also rubbing the

base of the lesion. 4. Vigorously swab the base of the de-roofed lesion with a sterile swab and return swab to tube. 5. The scalpel blade MUST be disposed into the appropriate sharps container. 6. Clearly label the swab and the specimen request form, INCLUDING the site of origin of the

HLA Typing for Transplantation HLA-typing for potential tissue or organ donor (also cross-reference with tissue typing) This important information must be given to the patient before collecting the blood samples: HLA-typing to determine suitability for a tissue or organ donor is not funded by Medicare. Usually the recipient's transplant physician will have applied for Federal Funding to search for donors and pay for the HLA-typing. WDP will be happy to collect the samples and courier them to Royal Perth hospital (at no charge). The donor will receive a bill from RPH for around $300 for the tests. This can be forwarded to the recipient's transplant centre for reimbursement. Alternatively the donor can contact the recipient's transplant centre for instructions on how to have the tests collected.

Mantoux [Tuberculin] - (Skin test for tuberculosis)

This test has a Special test out-of-pocket expense to the patient. Please refer to SPECIAL TESTS under “Billing” in this section for billing instructions and exceptions. You MUST inform the patient of this out of pocket cost Restricted to Trained and Accredited staff.

Principle

The Mantoux test is based on a delayed hypersensitivity (cell mediated immunity) reaction [erythema, induration] to intradermal injections of a sterile purified protein derivative [PPD] of a selected Mycobacterium tuberculosis organism. If there is a response, it is usually present in 48 hrs and may persist for up to 7 days. Quantitative tuberculin testing requires intradermal injection on the palmar aspect of the forearm. Precise intradermal injection resulting in a raised blanched wheal is necessary. The reaction is read 2-3 days after inoculation, and measured in mm.

Clinical significance

A positive reaction means that the patient is immune or infected or has been successfully vaccinated (BCG vaccine).

Specimen

The procedure is performed on the patient’s forearm, palmar aspect (i.e. palm facing upwards).

Reagents

PPD – Human (M. tuberculosis) 100 I.U./mL; 0.1mL dose contains 10 IU tuberculin

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 39 of 74

Equipment

I mL injection syringes with 0.1 mL graduations (do NOT use 2 mL syringes)

26 gauge needle

alcohol wipes

Procedure

Ask patient if has had previous TB skin test, and if so, whether there was a strong reaction. If a history of previous strong reaction, contact duty microbiologist before proceeding with test.

Use alcohol swab to clean palmar aspect (i.e. palm facing upwards) of forearm.

Identify middle third of forearm. Ensure there are no skin blemishes or scars in the vicinity. Identify an area where there are no superficial veins directly underneath the injection site. If necessary, make a temporary mark around the site for easy identification (both for administering the Tuberculin and for reading the reaction later).

Draw up 0.1mL (i.e. 10 units) of Tuberculin PPD. DO NOT USE TUBERCULIN PPD THAT HAS EXCEEDED ITS EXPIRY DATE OR BEEN USED ON A DAY EARLIER THAN THE CURRENT DAY. ALWAYS DISPOSE AMPOULE AT THE END OF EACH DAY.

NEVER RETURN NEEDLE OR ITS SYRINGE TO THE AMPOULE ONCE THE TUBERCULIN PPD HAS BEEN DRAWN OR THE PATIENT HAS RECEIVED THE INJECTION. Failure to observe this may result in serious cross-infection.

Intradermal injection: the uppermost layers of the skin are to be injected. The injection is not to be given subcutaneously as this will obscure any reaction. Care must be taken to ensure that the injection is not given into a vein. The needle is slid into the skin at a low angle, with the bevel facing upwards (see following diagram). The surrounding skin is held tight with your other hand. The needles should pass in deep enough for the hole in the bevel of the needle to just disappear. Slowly inject the 0.1 mL of Tuberculin PPD. This will cause a swelling of about 3mm diameter. If no swelling develops, then the needle is in too deep. If the fluid appears on the skin then you are not in deep enough. If either of these occurs, you must repeat the test on another site on the forearm at least 30mm away from the failed site, or on the other arm.

Mark the request form diagrammatically to indicate where and on which arm the Tuberculin PPD was administered.

Ensure that the form has been given a laboratory number and the test has been entered into the computer as a Mantoux test (panel code MK).

Give the patient a dummy test form with the laboratory number attached.

Make an appointment for the patient to return in 2-7 days (2 days is the preferred time) for reading of the reaction.

Results

The test is read 2-4 days (ideally at 48 hrs) after inoculation, by measuring the 2 transverse diameters (at right angles to each other) of the induration (hardness, lump) and taking the mean of the 2 measurements as the result. This is best done using a medium ball point pen (see diagram). Do NOT measure the erythema (redness) around the induration.

Borderline results (5-10mm) should be re-read at 72 hrs post-inoculation

Rarely a strong positive reaction (swelling, vesiculation, ulceration) may occur at the test site. The requesting doctor and duty microbiologist should be informed for symptomatic treatment if this occurs.

Document important patient history details regarding why the patient is having the test on the request form

e.g. history of BCG vaccination

history of exposure to TB history of TB and treatment for TB previous skin tests for TB travel history testing for employment purposes country of birth

Reference ranges

Traditionally, a “positive” reaction is greater than 10mm diameter of induration, a “negative” reaction is less than 5mm diameter, “borderline” is 5-10mm diameter.

Reporting

Results are reported on the MK panel Relevant patient history details as to why they are having the test should be recorded as a free text comment in the MK panel.

Mast Cell Tryptase

Tryptase levels in serum serve as an indicator of mast cell activation and as a marker of allergic mediator release, particularly in suspected cases of anaphylaxis. Blood samples are to be collected within 3 hours of an event occurring. Serum may be sent chilled, however, if not able to send within 48 hours it needs to be spun and frozen – some Doctors may request a one-off tryptase level, this can be taken at any time.

Melioidosis Culture

Blood - see Blood Culture for collection Sputum - see Sputum Culture for collection. Give patient Form P11 for collection instructions Pus - as submitted.

Methaemoglobin

1. Sample must be delivered to Mount Hospital Laboratory, Joondalup Laboratory, Hollywood or Peel Laboratories within 4 hours of collection. Contact the Duty Laboratory Manager to arrange transport.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 41 of 74

Patient consent forms and Clinical submission forms are helpful although not essential Testing can continue without these forms. Please sign tubes and request form. Place red Molecular Genetics sticker around the cap. Storage and transport: Specimens should not be frozen, exposed to excessive heat or remain in transit for extended times. Store in fridge or at room temperature (for shorter periods of time).

Mid Stream Urine

To collect a urine sample which is not contaminated by the bacterial flora which is in and around the urethral opening. When micturition begins the first part of the stream washes away the bacteria present in the lower urethra. Thus the "middle of the stream" is usually clear of contaminants. In post pubertal females the vulva may be so moist that secretions may enter even the midstream urine. Even such minute amounts of vulvo-vaginal secretions can cause false positive microscopic and culture results. Note that this problem is greater in obese and elderly women. These two factors do sometimes go together.

Collection NB: All urine specimens must be refrigerated until handed to courier. NB: Patient instruction forms are also available in a variety of languages. For cases where the

language is a barrier, please attempt to give the patient one of these forms.

NB: Where urines are collected at remote sites and are likely to take greater than 12 hours to arrive at a laboratory:

1. They must be refrigerated. 2. A Dip Slide culture must be inoculated. Store at room temperature prior to transport. 3. A cell count stain / preservative must be used.

Laboratory Managers are to facilitate these items.

The MALE The patient should wash hands thoroughly. Cleaning is not usually required. The uncircumcised male is instructed to retract the foreskin. The first burst of urine is passed into the pan. The paper cup / specimen collection jar is then passed into the stream of urine and half filled. The remaining urine is passed into the toilet. (It is preferable to collect mid stream while continuing to micturate. If this is too difficult the patient may stop and restart) The urine is then poured into the centrifuge tube up to the black indicator line. Close container lid firmly.

The FEMALE Give patient Form P12 for detailed instructions on collection. Mature Females: 1. Wash and dry hands thoroughly. 2. The labia are separated by the patient’s fingers of one hand and kept apart until the specimen has

been collected. 3. Using a sterile water swab the patient wipes over the urethral opening - from front to back.

Discard the swab. 4. Micturition is started allowing the first part to go into the pan. 5. Collect specimen from mid stream (preferably continuous) half filling the paper cup /specimen

container. Remaining urine is passed into the toilet.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 42 of 74

6. The urine is then poured into the centrifuge tube to the black indicator line. Close container lid firmly.

7. ALWAYS ask the female patient if she is menstruating and if so instruct her to insert a clean tampon after wiping and then wipe once again (with clean water wipe) collecting as above. Always mark the request form "PATIENT MENSTRUATING".

8. Store urine in refrigerator prior to transport to the laboratory. Note: Collectors should offer to help any patient they suspect may experience difficulty. This may require holding the container in position with a gloved hand.

Prepubertal Females Specimen is collected as above but step ii. (cleaning) can be omitted. Give patient (or guardian) Form P12 and make a cross through step 2 diagram. Paediatric Collection Ensure genital area is free of creams and lubricants. 1. Remove paper backing to expose adhesive.

2. For female use, place opening of bag as to cover upper half of genitalia. 3. For male use, the penis must be projected through the opening of the bag.

Remove P2 mask (suitable for single-use only)

Perform hand hygiene

7. COMPLETE REQUEST FORM.

Nasopharyngeal Aspiration (NPA)

This procedure is designed to collect fluid and epithelial cells from the nasopharynx. A soft polythene catheter is used. It is less traumatic than a swab. For the patient, it is unpleasant but painless. It may make the patient cough, which can spread virus droplets. For this reason, the collector must wear adequate personal protective equipment (PPE). This method provides a useful diagnostic specimen for the diagnosis of infection with Bordetella pertussis (whooping cough), Mycoplasma pneumoniae, influenza and other respiratory viruses. 1. OBTAIN MATERIALS

Suction kit (check expiry date and packaging) – size 8 (code 452-08-007). Suction pump with tubing

Sterile saline

Tissues

Personal protective equipment (PPE) for the health care worker (HCW): gown, gloves, eye protection (goggles or face-shield), P2 mask (surgical masks don’t give adequate protection), and hand hygiene products

2. PREPARE ROOM

Hand hygiene: alcohol-based hand cleanser or handwashing facilities

Assume everything in the room will be contaminated by viral particles 3. PREPARE HEALTHCARE WORKER

Do this before entering the room with the patient

Perform hand hygiene. Put on PPE: gown, P2 mask (perform fit check), goggles/face-shield, and gloves

4. PREPARE THE PATIENT AND/OR THE PATIENT’S PARENT

Explain the procedure to the patient.

5. SPECIMEN COLLECTION

Note on the request form if the patient has consumed anything with in the last half-hour.

Assemble the suction set and pump, ensuring all fittings are firm and are not leaking air

Small children should sit on parent’s (or assistant’s) knee with the child’s back to the parent. Older children or adults can sit on a chair or lie down.

Raise child’s arms so that the upper arms press against their ears and their hands are behind their head. The parent grasps the hands firmly and is instructed not to let go. Older children or adults may place anywhere that is comfortable.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 48 of 74

Estimate the length of catheter required to reach the nasopharynx – this is approximately equal to the distance between the nose and the ears. You may wish to mark the catheter for this distance.

Insert the catheter into one nostril until it reaches the nasopharynx

Apply suction and rotate catheter – continuing this while is it slowly withdrawn. The suction can either be started once the catheter reaches the nasopharynx or it can be started beforehand with the tubing kinked until suction is required.

Give the patient some tissues at completion of collection

Once the catheter is removed, there will be a small volume of fluid and epithelial cells in the distal 1 – 2 cms.

Suck not more than 0.5 mL of sterile saline into the trap. This will flush the specimen into the trap.

Remove the tubing and put the lid on the trap, which is now the specimen container.

Label the specimen container with patient name, collection date and source (nasopharyngeal aspirate)

Place specimen tube in specimen bag. 6. REMOVE PPE

Do this after leaving the patient’s room

Remove gloves first and discard, perform hand hygiene

Remove goggles/face-shield and gown, perform hand hygiene

Remove P2 mask (suitable for single-use only)

Perform hand hygiene 7. COMPLETE REQUEST FORM

Refrigerate specimen until sent to the laboratory.

Nasopharyngeal Swab

The purpose of the swab is usually as for a nasopharyngeal aspirate. The swab is inferior to the aspirate in terms of the volume of diagnostic material, and what tests can be done, however, when suction is unavailable for operating a mucus trap this is an adequate substitute. It is recommended that if the patient is able, then attend a collection centre. This swab is not suitable for Bordetella pertussis IgA. An SST must be also be collected for Bordetella pertussis IgA serology.

Neonatal Bilirubin

The preferred sample type for measurement of bilirubin in neonates and infants up to 1 month of age is a red topped clot tube. A dark green topped lithium heparin tube without gel may also be used, however SST’s and PST’s (types containing gel) should be avoided as the use of these tubes can result in less yield of serum/plasma and can often require a recollect. If possible the tube should also be full (600 uL in a paediatric tube) to avoid the need for recollection.

Scraping – Hair

To facilitate the work of the diagnostic laboratories, the following data should be requested for all specimens: 1. Patient name, age, sex 2. Type of specimen (eg:- nail scraping) 3. Anatomical site from which specimen is taken. 4. Short description of lesion. 5. Has patient had any topical treatment or did he/she take any oral antifungal agents? 6. If the answer is "YES", contact a Clinical Microbiologist before collection of specimen. NB: An accurate diagnosis of fungus infections can only be made when adequate

specimens are obtained. Poor quality specimens can often result in incorrect information.

Procedure

1. Collect equipment - sterile jar - yellow top. - scalpel blade No. 22 or No. 23 - alcohol swab - gloves 2. Clean skin thoroughly with 70% alcohol swab. 3. Collect any hairs that are broken off, or attached to crusts within inflammatory areas

or that fluoresce with a bright green-yellow or green white colour under ultra violet light.

4. Remove hairs by the roots from scalp or beard using sterile forceps. Hair clippings should be obtained from affected body hairs. Cut as near to the root as possible.

5. Place at least 10 - 15 pieces of hair in a sterile container.

Scraping - Nail

To facilitate the work of the diagnostic laboratories, the following data should be requested for all specimens: 1. Patient name, age, sex 2. Type of specimen (eg:- nail scraping) 3. Anatomical site from which specimen is taken. 4. Short description of lesion. 5. Has patient had any topical treatment or did he/she take any oral antifungal agents. 6. If the answer is "YES", contact a Clinical Microbiologist before collection of specimen.

Procedure

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 57 of 74

1. The specimen should be taken from nails which are thickened, discoloured or show a chalky, crumbling appearance.

2. Clean nail thoroughly with 70% alcohol to remove surface micro-organisms. Allow to dry.

3. Scrape as much debris as possible from the under surface of the nail into container or into envelopes. The nail is dead and nerveless - you will not hurt the patient.

4. Obtain as many nail clippings as possible from the infected area and collect specimen in envelope or container.

5. In the presence of exudate in connection with inflamed paronychial tissue, collect exudate by using two swabs. Use one to make a smear and place the other (for culture) in Stuart's transport medium.

Scraping – Skin

To facilitate the work of the diagnostic laboratories, the following data should be requested for all specimens: 1. Patient name, age, sex 2. Type of specimen (eg:- nail scraping) 3. Anatomical site from which specimen is taken. 4. Short description of lesion. 5. Has patient had any topical treatment or did he/she take any oral antifungal agents? 6. If the answer is "YES", contact a Clinical Microbiologist before collection of specimen NB: An accurate diagnosis of fungus infections can only be made when adequate specimens are obtained. Poor quality specimens can often result in incorrect information.

Procedure

1. Collect equipment - sterile jar - yellow top. - scalpel blade No. 22 - alcohol swab - gloves 2. Clean skin thoroughly with 70% alcohol swab.(The alcohol only affects surface

organisms and will not harm the fungi in the layers). Allow the alcohol to dry. 3. Scrape lesion with sterile scalpel blade and collect as many scrapings as possible in

sterile container (yellow top jar). 4. If several lesions are present, scrape several (3 or 4) of them. INCLUDING THE

MOST RECENT ONE. 5. When lesion is round (as in lesions caused by ringworm fungus) with a red and/or

vesicular border and a healing centre, scrape edge of the lesion where the actively growing fungus will be found.

6. When lesion is VESICULAR, remove top of vesicle with a scalpel blade and include it as part of the specimen.

7. When lesion is red, moist and painful (as in Candida infection) scrape the edge of the lesion if possible. If scraping causes too much discomfort to the patient, then collect dried scales from the surface of the lesion.

8. In INTERDIGITAL (Toe Spaces) LESIONS: After cleaning area with 70% alcohol and allowing it to dry, remove as much dead white macerated epidermis from the top of the lesion as possible then scrape and collect the growing edge of the lesion.

9. In the presence of exudate, collect two swabs from the area. Use one to make a smear and place the other swab in Stuart's transport medium or in a test tube containing a small amount of sterile water to prevent it from drying out. Dry swabs should not be sent.

10. In general, swabs are not the best way to collect specimens. Most pathogenic fungi cannot be isolated from specimens collected by swabs: however, using swabs for

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 58 of 74

collecting oral, vaginal and rectal specimens (as in yeast infection) is practical and convenient.

11. Send collected samples to the laboratory as soon as possible, as some fungi may not survive for an extended period.

Secretory IgA

Saliva – Patient not to eat for 1 hour prior to collection, see below for collection method.

Procedure

Saliva collection. 1. Place a sterile cotton wool ball near the opening of the parotid salivary duct (ie

between the upper gum and the cheek as far back as possible). The child or parent can do this.

2. Keep the cotton wool ball in place for 5-10 minutes until “wet”. With small children, it may be necessary to hold the cotton wool ball in place.

3. Remove cotton wool with forceps or use fingers if the child feels threatened by the forceps.

4. Place the wet cotton wool in a 5mL syringe from which the plunger has been removed, replace plunger then squeeze saliva from cotton wool into a 3DT tube.

5. Store at 4oC. NB Avoid being bitten.

Semen Analysis – Patient Instructions

POST VASECTOMY: Samples may be dropped of at any ACC. Patient Information instructions (supplied by Doctor but also contained in your

Forms File Manual) state that patients contact the ACC to arrange a drop off time.

Arrange this time close to your courier pick up. This is important as samples need to be analysed ASAP. FERTILITY SAMPLES: Only certain ACC’s can receive semen samples for fertility. These are

locations where there is a microscope and trained staff to assess the sample – see attached Patient Information Sheet.

Collector to pass specimen to appropriate Scientist at their location to perform the motility.

The Scientist will then forward the sample to Myaree. If patients present at your ACC and you are not listed on Patient Information

Sheet to receive fertility samples, please contact Duty Manager at Myaree on 9317 0814.

The patient should ring the collection centre to arrange a suitable time and place to bring in the specimen. NOTE: No more than 30 minutes should elapse between collection and delivery to the collection centre as timely examination by the laboratory is required to prevent potential deterioration of the specimen.

Collection of Semen Samples 1. Patient is to be given Form P5 for patient instructions and information. 2. Collect specimen between three and seven days after your last ejaculation. 3. Collect the ENTIRE sample by means of masturbation. Other methods such as

interruption of intercourse are not suitable as there can be a loss of the first portion of the specimen.

4. DO NOT use condoms, artificial lubricants, talc’s etc., as these will interfere with the test.

5. Collect the specimen in the specially provided container previously allowed to reach room temperature. DO NOT expose the specimen to extremes of temperature eg:- refrigeration.

Keep at room temperature, generally 20oC. 6. Write patient surname and given name on the label of container, plus date and time

of collection. 7. Specimen should be delivered to the Laboratory or Listed Collection Centre (not at

other specimen collection centres) within 30 minutes of collection. 8. Collection at the Laboratory

The patient may elect to produce the specimen at the laboratory or collection centres. i. Patients are entitled to secure privacy while producing the specimen. ie:- Put

the patient in a room (not a toilet) with blinds/curtains and lockable door. If this facility is not available, refer patient to a more appropriate centre.

ii. It is inadvisable to allow the patient to produce the specimen on site if you are alone.

9. Any questions or discussion with the patient should be carried out discreetly. It is

probably very embarrassing for him. 10. All semen analysis request forms are to be labelled with "Process Immediately"

stickers.

Serotonin (Serum)

1. Collect 1 x Clot (red top). No gel. 2. Centrifuge, separate and freeze ASAP at LCC 3. Transport frozen sample to Sydney Pathology.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 60 of 74

Serotonin (Platelet)

1. Collect 4.5mL EDTA (Purple) x 2. Do NOT centrifuge or refrigerate the sample. 2. Specimen must be sent to RPH, Haematology within 12 hours of collection. 3. On Friday specimen must be at RPH by 15.00 hours. Do not collect Saturday,

Sunday or Public Holidays. 4. Collect specimens in the morning. Contact Duty manager to arrange transport.

Snake Venom Detection

1. Performed at Joondalup laboratory. 2. Sample can be blood, urine or a swab from the snake bite site - contact Duty

Biochemist. 3. Patient should be referred to the nearest hospital.

SOLVS (Self Obtained Low Vagina swab) APTIMA swab

collection for Chlamydia, Gonorrhoea & Trichomonas

vaginalis PCR or culture

1. Remove excess mucus from the cervical and surrounding mucosa using the APTIMA cleaning

swab (white shaft in the package with red printing). Discard this swab. 2. Insert the APTIMA specimen collection swab (blue shaft swab in the package with the green

printing) into the cervical canal. 3. Gently rotate the swab clockwise for 10 to 30 seconds in the endocervical canal to ensure

adequate sampling. 4. Withdraw the swab carefully; avoid any contact with the vaginal mucosa. 5. Remove the cap from the swab specimen transport tube and immediately place the specimen

collection swab into the APTIMA transport tube. 6. Carefully break the swab shaft against the side of the tube at the scoreline and discard the top

portion of the swab shaft; use care to avoid splashing of the contents. 7. Re-cap the APTIMA swab specimen transport tube tightly. 9. The endocervical swab for gonococcal smear and culture is another blue top tube- transport

swab. Take the swab and roll it through 360 in the endocervical canal, remove the swab and roll it on a labelled, clean glass slide before placing it in the transport medium of its original tube. Make sure the tube is properly labelled.

Doctors frequently ask for both an endocervical swab (ECS) and a high vaginal swab (HVS).

Collection of vaginal swabs other than High Vaginal Swabs

This may be a useful investigation of a child with vaginal irritation or discharge. In the adult, the preferred technique is to use a speculum and under direct vision collect the HVS and ECS. In children being investigated for possible gonorrhoea or chlamydia, a vaginal swab is sufficient, as the cervix is not infected before puberty, hence speculum examination and endocervical swabs are usually not necessary. The child with vaginal irritation may be infested with threadworm. During collection a worm may become visible. If so, collect the worm on a swab and place in a sterile container for identification in the laboratory.

Procedure 1. This should be as for adults, although very small children may be happier on their mother’s

lap. Make sure you have good visualization before proceeding. 2. Part the labia with the fingers of your gloved left hand. 3. Use a blue top ‘Transport’ swab, you will discard the tube.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 61 of 74

4. Gently insert the swab approximately 20 mm into the vagina 5. Roll the swab over the entire circumference of the vaginal wall 6. Withdraw the swab and make a smear for microscopy on a labelled glass slide. 7. Take a second blue top swab for culture for gonorrhoea and place the swab into the

Transport tube. 8. If Chlamydia and/or Gonorrhoea is requested, take a third swab (APTIMA blue shaft swab in

the package with the green printing) and after swabbing, place in a APTIMA transport tube. Note: Remove the cap from the swab specimen transport tube and immediately place the specimen collection swab into the transport tube. Carefully break the swab shaft against the side of the tube at the scoreline and discard the top portion of the swab shaft. Re-cap the swab specimen transport tube tightly.

Sperm Antibodies

Tests for sperm antibodies are usually performed on a sample of blood from the female partner, but occasionally from the male. Specimen: Collect 1x SST In the case of Dr. Ann Jequier’s [JEQJ] patient’s all male partners have the sperm antibody test performed on their semen sample only, and never on their blood sample. Female patients of Dr. Jequier do not have a sperm antibody test. Rarely the doctor may request a test for sperm antibodies on cervical mucous. Specimen: Semen is collected as for Semen Analysis-Infertility. Specimen: Cervical mucous. This is a doctor collect only. Contact the Medical Microbiologist on duty.

Sperm Washing

Sputum Culture

In medical terms, sputum is the material coughed up from the bronchial tubes. The sputum in a patient with bronchitis or pneumonia will appear purulent (as pus, cream-yellow to green-yellow) and it may appear blood streaked. When the patient coughs sputum into the mouth it becomes surrounded by saliva before it is coughed into the specimen container. This causes difficulty because many of the organisms in the mouth and throat are the ones which cause bronchitis and pneumonia. In the laboratory, the purulent matter (pus) is removed from the clear saliva and cultured to identify the micro-organisms. NB: Sputum sample quality deteriorates at ambient temperature. It is important to refrigerate until sent to the laboratory. Before the patient commences explain the steps of the procedure as listed in the

"Sputum Specimen Collection Information" sheet - Form P11.

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 62 of 74

On receipt of the specimen 1. Examine the sample through the container, if it appears clear, ask the patient to try

again. 2. Send the original specimen to the laboratory and note on the request form that a

second specimen has been requested. 3. If the second specimen is not satisfactory, note on the request form that this is a

second specimen, collected after advice to the patient. The laboratory will then contact the doctor to suggest an alternative method of collection such as naso-pharyngeal aspiration.

Sputum for Cytology

1. Instruct the patient to collect the specimen as per the Sputum Culture method. 2. The specimen should be kept refrigerated until transport to Myaree. 3. Do not add anything to the specimen. NB: Where Sputum Cytology x 3 is requested, it is recommended that x 3 (three) samples be collected on consecutive days. Where possible, ensure each specimen is sent to the Myaree lab on the day it was taken. If delays are likely, make sure the specimen is kept refrigerated. NOTE: If Doctor did not request sputum x 3 do not collect 3 specimens. Only collect one specimen.

Sweat Test

1. Performed at Princess Margaret Hospital. 2. Patient needs to make an appointment at the Clinical Investigational Unit. 3. Suggest Duty Biochemist speaks to doctor.

Synacthen Stimulation

This test requires a baseline ACTH and Cortisol level with a 30min and 60min cortisol level. This test must be done by a Medical Practitioner competent in resuscitation and with appropriate resuscitation equipment available on hand. For this reason we cannot offer the test at Myaree. Please contact Duty Biochemist before proceeding with booking as detailed below. This service is offered at Joondalup on Mon, Wed and Friday mornings by Dr S. Ward. Patients are required to make a booking with his receptionist on 9400 9060 to ensure Dr Ward is available. If the test is for Synacthen Stimulation/17OH-Progesterone then collect as per above and take an extra SST (spin within 2 hours) for the sample 17OH-Progesterone.

Throat Swab M C & S

The pathogenic organisms are most likely to be found in the tonsil (or bed if tonsils have been removed) or on the back wall of the throat. When the tonsils or throat are rubbed firmly with a swab the patient will nearly always "gag". (If they do not gag you probably have not been firm enough). It is very important to have a clear view of the tonsils and throat so that you can quickly take the sample before the patient "gags". Procedure 1. Have a good light and a tongue depressor (wooden) available. 2. Request the patient to extend the tongue with the jaw wide apart. 3. Press the patient's chin down with your non-dominant hand. 4. If you have a good view take the swab with your dominant hand. 5. If the view is restricted ask the patient to wobble the tongue from side to side and

then extend it again. 6. If the view is still restricted you will have to use the tongue depressor. Place the

depressor on to the middle of the tongue approximately half way back, using your non-dominant hand. Press the tongue down gently and this should give a good view.

7. If the depressor is too far forward the back of the tongue heaps up making visualisation even worse. On the other hand if it is too far back the patient will "gag".

Sampling Ideally use the swab to rub one tonsil, then across the back of the throat and then the other tonsil on the way out. According to the patients reaction you must judge whether to make a second attempt. Do not be afraid of "being cruel to be kind". The patient wants an answer to their problem.

Urine Collection - (24 hour)

Precautions For Urine Collection All 24 hour urine’s requiring acid are to be collected into jars containing 20mL 50% HCI. Please noted that it may be necessary to collect 2 x 24 hour urine’s eg. A request for urinary magnesium and uric acid. Spot urine’s need to have pH adjusted to <3. Due to the dangerous nature of HCI, warning stickers should be placed onto the urine container and the patient needs to be told that the jar contains acid and as such to exercise caution. An initial quantity of these stickers will be supplied to relevant sites and subsequent supplies can be ordered through stores.

Regional laboratories should source HCI through local suppliers and the Metro area should be co-ordinated through the major collection centres where acid can be supplied via Myaree. For LEAD - 24 hour urine - contact Duty Biochemist PRIOR to collection. Test only performed when patient on chelation. Do blood lead instead. 1. The patient is given a clean 24 hour urine container with their name and the test

required printed clearly on the label. 2. Give patient Form P8 - 24hr Urine Collection instructions. 3. When collection is to commence, patient should empty bladder into the toilet, note

the time, and write this clearly on the label with the date for Day 1. 4. From this time on, all urine passed for the next 24 hours is collected into the

container. 5. On Day 2, patient should empty bladder at the same time as commencing the 24

hour collection. This sample is placed in the collection container. 6. Patient writes date and time of completion on label and returns same to Pathology. 7. If urine has to have a preservative added, do this carefully before giving container to

patient. Print in large RED letters that ACID has been added and warn the patient NOT to urinate directly into the container.

Also warn patient not to leave container around children or animals. Collect specimen as above.

8. If request for 24 hour urine is for both (No Preservative and Preservative), two separate 24 hour collections must be obtained.

NB: Ideally, 24 hour urine collections on females should NOT be collected during

menstruation. If there are extenuating circumstances or the request form is marked URGENT, contact the Duty Biochemist.

Urine Collection - Split 24 hours

1. Contact Duty Biochemist to confirm details. 2. Give patient Form P10 - Split 24 hour Urine Collection instructions.

Urine Collection - Timed

1. Give patient Form P9 - Timed Urine Collection instructions. 2. Patient empties bladder into the toilet immediately prior to going to bed. The time is

recorded on the container (eg:- 10.00pm) 3. All urine passed during the night and including that passed on waking the next

morning is collected into the container. 4. The time of the last morning specimen (eg:- 7.00am) is recorded on the container.

Urine Cytology

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 70 of 74

1. Instruct the patient to collect a urine sample from the 2nd specimen of the morning. A yellow topped MSU jar can be used for this.

2. The specimen should be kept refrigerated until transport to Myaree. 3. Do not add anything to the specimen.

NB: Where urine cytology x3 is requested, it is recommended that x3 (three) samples be collected on consecutive days. Where possible, ensure each specimen is sent to the Myaree lab on the day it was collected. If any delays are likely, make sure the specimen is kept refrigerated. NOTE: If Doctor did not request urine x 3 – DO NOT collect 3 specimens. Only collect one specimen. A spot urine in these circumstances will be sufficient if the patient can produce the specimen on site, otherwise, get them to collect a sample from the 2nd morning specimen as per instruction 1 above.

Urine for PCR – Gono/Chlamydia/TV (APTIMA)

First Stream Urine is the term for the first 10 to 20 mL which comes out as urination commences. This initial volume of urine contains a high concentration of micro-organisms flushed out of the urethra. It is critical that the specimen is not too large as the micro-organisms have the potential be diluted beyond the limits of detection if too much urine is obtained. A First Stream Urine is unsuitable for the diagnosis of bladder or renal infection. The more usual Mid Stream Urine sample is not suitable for the PCR diagnosis of infections caused by Chlamydia trachomatis and Neisseria gonorrhoeae. PCR for Chlamydia trachomatis , Neisseria gonorrhoeae & Trichomonas vaginalis (TV) on First Stream Urine is very sensitive but may occasionally be negative, for example in some women with infection confined to the endocervix. A PCR test may remain positive for several weeks after successful treatment, as dead and damaged organisms may clear slowly. Confirmation of previous positive results may still be possible in these circumstances and may be relevant to counselling. The accuracy of PCR is high, but not a complete substitute for the established conventional methods. The clinician strives to detect all infections. The use of several different types of test allows enhancement of diagnostic accuracy. Procedure 1. Ideally, the patient will not have passed urine for at least an hour. 2. The patient should be instructed to retract the foreskin (males) or spread the labia

(females) and urinate into a sterile container. 3. Before the procedure show the patient an identical urine container holding the

required volume of urine (10 to 20 mL). Mark the upper limit of required urine on the outside of the container. Collection of larger volumes of urines may result in target dilution that may reduce test sensitivity. Female patients should not cleanse the labial area prior to providing the specimen.

4. Transfer approximately 2mls of urine from the yellow top jar to the APTIMA specimen transport tube using the sterile pipette supplied. The correct volume of urine has been added when the fluid level is between the black fill lines on the urine specimen transport tube label – visible in the window of the APTIMA transport tube.

5. Reseal the jar and the APTIMA tube tightly.. 6. When barcoding the specimens apply one barcode label to the APTIMA and attach it

with an elastic band to the yellow top jar. Please ensure that the yellow top and

Western Diagnostic Pathology Copyright - Copying is Not Permitted. ISSUE 17. Section 3, Page 71 of 74

APTIMA tube are properly labelled and both containers properly sealed before transport to the laboratory.

Minimum level of urine required in yellow top jar - to the AM/PM line. Urine in the APTIMA transport tube must be between the line in clear window.
