Rapid Strep A Testing: Overview Pharyngitis, can be caused by streptococci from

serogroups other than Group A, as well as other pathogens. The rapid strep test will not detect these other groups and pathogens.

The Quick Vue ® Strep test will not differentiate asymptomatic carriers of Group A Streptococcus from those exhibiting streptococcal infection.

The test is designated as a screening test at WellOne since, if clinical signs and symptoms are not consistent with test results, follow-up laboratory performed culture procedure should be performed.

previous slide

The correct answer is FALSE

The rapid strep test is 92% sensitive (meaning that 8 out of 100 persons with strep throat will have a negative rapid strep test)

If clinical signs and symptoms are not consistent with test results, follow-up laboratory performed culture procedure should be performed.

Reagents should be stored at room temperature, in the laboratory 59 F -86F (15 C -30C) and out of direct sunlight. The laboratory room temperature must be checked daily and action taken for out of range temperatures.

Kit contents are stable until the expiration date printed on the outer box.

Swab specimens should be processed as soon as possible after collection and the test kit not opened until just prior to testing.

The Test Cassette must remain sealed in the protective foil pouch until just prior to use.

Rapid Strep A Testing: Storage and Stability

Each test kit comes with two control swabs (one positive and one negative) that must be checked prior to use of a new box of tests

Be sure that controls have been run and are acceptable for the test kit that you are using prior to patient testing

If results are not as expected (ie. Positive control is negative and/or negative control is positive) DO NOT USE BOX. Segregate box of tests and notify supervisor immediately.

Document the results of control testing on the strep testing log form

Use a new log form for each new box of tests opened

Steps in Testing: Collecting the Specimen Collect the specimen: Use ONLY the

swabs supplied with the test kit for Strep testing (these swabs have a green handle)

Avoid the uvula as stimulation may result in gagging

Take the sample from both sides of the throat at the tonsillar areas

Stand off to the side of the patient to collect the specimen (helpful if the patient coughs or gags) Click here to

previous slide

The specimen should be collected from:

The uvula

The posterior gyros

Both sides of the tonsillar areas

Steps in Testing: Testing the sample Inspect the extraction solution bottle and

do not use if the solution is not clear. DO NOT USE EXTRACTION SOLUTION IF IT IS GREEN PRIOR TO BREAKING AMPULE.

Squeeze carefully to crush the glass ampule inside the extraction solution bottle.



previous slide

Steps in Testing: Testing the sample Vigorously shake the bottle 5 times to

mix solution. Solution should turn green after the ampule is broken (do not use if green color is not present).

Solution must be used immediately.

The extraction solution bottle should be crushed and __________ prior to use.

shaken vigorously 5 times

warmed

cooled

frozen

The extraction solution before crushing should:

Be clear green

Be pink

Contain a green hue

Be Clear

The correct answer is be

clear….. If the solution is GREEN before crushing, the ampule has already been crushed before you handled it.

Since the solution must be used immediately after mixing, the extraction bottle must be discarded. Click here to

The correct answer is clear and green

Before crushing and mixing the ampule, the extraction solution should be

After crushing and mixing the ampule, the extraction solution should be clear (not cloudy) and

Steps in Testing: Testing the sample

Remove the cap from the bottle and quickly fill the chamber to the rim.

Begin timing (5 minutes) If liquid has not moved across the

Result Window in 1 minute, completely remove the swab and re-insert. If liquid still does not move across, retest with a new specimen, Test Cassette and Extraction Solution Bottle.

The Test Cassette should not be moved until the assay is complete.

Steps in Testing: Interpreting Results Positive Result:The appearance of any pink - to purple line next to

the letter “T” in the Result window, along with the blue control Line next to the letter “C” means that the test is positive for group A Streptococcus.

C for control Even a light line at the T is positive

T for TestClick here to go back and review

Steps in Testing: Interpreting Results

The Control line is vivid blue- indicating an acceptable test

The Test line is light pink indicating a positive test


previous slide


Steps in Testing: Interpreting Results Negative Result:The appearance of only the blue control Line

next to letter “C” in the Result Window means that the test is negative. A negative QuickVue ® result means that the swab is presumptive negative for group A Streptococcus. A line at the C= acceptable test

No line at the T= negative test Click here to go

A blue control line next to the letter C means that:

The test is positive

This was a “good” (or reliable) test

The patient has strep throat
