The Apolipoprotein Evaluation is a series of tests used to measure various apolipoproteins in the blood, which are protein components of lipoproteins that transport cholesterol and triglycerides. Common apolipoproteins measured include Apo-A1 (associated with HDL or “good” cholesterol) and Apo-B (associated with LDL or “bad” cholesterol). The evaluation provides a more detailed understanding of lipid metabolism and helps assess the risk of cardiovascular diseases, such as heart disease and stroke. This test is often used to supplement traditional lipid profiles and can help in managing lipid disorders or monitoring the effectiveness of lipid-lowering treatments. A blood sample is required for this test.
