ApoB

ApoB counts the actual number of atherogenic lipid particles in your blood — including LDL, VLDL, and Lp(a) carriers — and many cardiologists treat it as a more accurate cardiovascular risk marker than LDL alone.

Reference range

Watch points

Critical: at or above 130 mg/dL
High: at or above 120 mg/dL
Borderline: at or above 100 mg/dL

Same thresholds apply to men and women in this table.

Why hard-training athletes watch it

A lifter can show a normal LDL-C but an elevated particle count — a common pattern on a very high-fat diet — and ApoB is the marker that catches what LDL-C alone can miss.

When to retest

Order it alongside your regular fasting lipid panel every 3–6 months if your clinician is tracking cardiovascular risk more closely.

Talk to your clinician

Discuss your atherogenic particle count (ApoB) and lipid management with your clinician. This is a more specialized marker — bring it to a clinician comfortable interpreting particle-based lipid testing rather than relying on LDL-C alone.
