ApoB vs LDL-C

ApoB counts every atherogenic particle (LDL, VLDL, IDL, Lp(a)). LDL-C estimates cholesterol mass inside LDL particles. When the two diverge — common in metabolic syndrome and insulin resistance — ApoB is the more accurate cardiovascular risk marker.

Choose ApoB

ApoB is the preferred decisional marker for cardiovascular optimization, especially with metabolic syndrome, insulin resistance, or discordant lipids.

Choose LDL-C

LDL-C remains useful as a trend marker and for continuity with historical labs.

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

If LDL-C is normal, do I still need ApoB?

Yes — discordance between LDL-C and ApoB is common and only ApoB resolves it.

Is ApoB on the standard panel?

It is included in the extended lipid panel reviewed during cardiovascular-anchored optimization.

Next step

Take the optimization assessment.

The adaptive assessment maps your symptoms, history, and goals to candidate pathways — and routes you into provider review.
