Apolipoprotein A1 and B, Serum

Use

This test is useful for assessing cardiovascular risk by providing levels of Apolipoprotein A1 and B, both of which are critical components of the lipoprotein structures. Apolipoprotein B is the main protein in low-density lipoproteins (LDL), commonly known as bad cholesterol, linked with the buildup of atherosclerotic plaques. Conversely, Apolipoprotein A1 is the main protein in high-density lipoproteins (HDL), referred to as good cholesterol, which helps remove cholesterol from the bloodstream. A balance measured through this test helps to evaluate the risk of cardiovascular disease even more accurately than traditional lipid panels, especially in individuals with a significant family history of coronary artery disease or those with lipid measures that do not correlate with clinical presentations.
