ApoB
Apolipoprotein B – atherogenic lipoprotein particle count
Also known as
Apolipoprotein B ApoB-100
Definition
ApoB is the structural protein of all atherogenic lipoproteins (LDL, VLDL, IDL, Lp(a)) and represents the total number of particles capable of causing atherosclerosis. It is a superior risk marker versus LDL cholesterol because each particle can damage the arterial wall regardless of its cholesterol content. The ESC recommends ApoB testing in individuals with elevated cardiovascular risk.
