Test your ApoB in Orange County.
ApoB plus 100+ biomarkers for $190, drawn at lab locations across Orange County.
ApoB is essentially a more accurate LDL. ApoB measures the total number of atherogenic (artery-damaging) particles in your blood. Each LDL, VLDL, and IDL particle carries exactly one ApoB molecule, making it a direct particle count. This is important because it is the number of particles, not just the amount of cholesterol they carry, that drives plaque buildup. About 15-20% of people have elevated ApoB with normal LDL cholesterol, which is why ApoB catches risk that a standard cholesterol panel misses. The 2026 AHA/ACC guidelines now include ApoB targets alongside LDL.
