03.WhatDoesCholesterolDoo?Cholesterol helps carry digested fat from the liverto the whole body. The blood vessels act as ahighway.Afterfulfillingthisfunction,cholesterolreturnstotheliverandrepeatstheprocessalloveragain.

The liver loads the fat on to the VLDLs. These travel through the blood vessels, unloading fatthroughoutthebody.TheemptyVLDLsthenbecomeLDLs.

LipoproteinSubfractionTesting

It is done to help evaluate your risk of developing coronary artery disease (CAD). Lipoproteinsubfraction tests of LDL are done based upon their size, density, and/or electrical charge.Lipoproteins are heterogeneous particles – containing molecules of proteins, cholesterol,triglycerides andphospholipids.As theycirculate in thebody,variousmolecules are removedand
