About ApoB
ApoB (Apolipoprotein B) is a protein that coats every atherogenic lipid particle — LDL, VLDL, IDL, and lipoprotein(a) — making it a direct count of cardiovascular risk particles rather than just the cholesterol they carry. Evidence consistently shows that ApoB is a better predictor of heart attack and stroke risk than LDL cholesterol alone, particularly in people with insulin resistance or high triglycerides. Major cardiology guidelines increasingly recommend ApoB as the primary lipid biomarker.
