ApoB — Cardiovascular Risk Marker
ApoB is the protein that carries LDL, VLDL and other plaque-forming particles. Cleveland Clinic calls the test likely more accurate than a standard lipid panel.
An apolipoprotein B (ApoB) test measures the protein that carries LDL, VLDL and other particles that help make plaque in the arteries, and it is used to gauge the risk of heart and blood vessel disease. Cleveland Clinic notes it is likely more accurate than a standard lipid panel.

ApoB counts every particle in your blood that can lodge in an artery wall.

The biomarker
- Name: ApoB
- Units: mg/dL
- Standard reference range: about 50–150 mg/dL (ranges vary by lab)
- Target: < 100 mg/dL — the ideal level per Cleveland Clinic
How to read your result
| Value | Interpretation |
|---|---|
| < 100 | Ideal level, per Cleveland Clinic |
| 100–130 | Above the Cleveland Clinic ideal level — discuss with your clinician |
| > 130 | Higher risk of heart and blood vessel disease, per Cleveland Clinic — see your clinician |
What moves the needle
- Diet. Limit saturated fat as part of a heart-healthy eating plan (NHLBI).
- Movement. Regular physical activity, which NHLBI notes can lower LDL cholesterol.
- Medication. If your ApoB is elevated, your clinician will consider the same treatments used for high LDL cholesterol (Cleveland Clinic). Do not start or change medication without a clinician.
Why this test is worth asking for
- ApoB rides only on LDL, VLDL and related particles — the ones that carry substances that help make plaque.
- Cleveland Clinic describes the ApoB test as likely more accurate than a lipid panel for judging heart and blood vessel risk.
- It is most often ordered to help work out the cause or specific type of high blood cholesterol — ask your clinician whether it adds to your lipid panel.
