Apolipoprotein B

Apolipoprotein B (ApoB) is the primary protein on the surface of all potentially atherogenic lipoprotein particles (LDL, VLDL, IDL, Lp(a)). Measuring ApoB provides a direct count of these particles, which is considered by many longevity experts to be a superior predictor of cardiovascular disease (ASCVD) risk compared to LDL-C alone, as it reflects the particle concentration driving atherosclerosis. Lowering ApoB to optimal levels is a key strategy in ASCVD prevention. Ranges assume no underlying medical conditions such as prior heart disease.
