Apolipoprotein B

A count of the atherogenic particles in your blood, since every LDL, VLDL and Lp(a) particle carries exactly one apolipoprotein B.

Unit mg/dLTypical adult range 80–155 mg/dL
What it is

A count of the atherogenic particles in your blood, since every LDL, VLDL and Lp(a) particle carries exactly one apolipoprotein B.

Why it matters

Two people with the same LDL cholesterol can carry very different numbers of particles, and the particle count tracks risk better than the cholesterol they carry.

Reading the number

Where it disagrees with LDL, it is usually the more informative of the two -- particularly when triglycerides are high and the calculated LDL is unreliable. Unlike LDL it barely moves with fasting.

When to raise it

Worth discussing when it reads high despite an LDL that looks acceptable.

Tracking only, not a diagnosis. The range above is a typical adult reference range — the range printed by the lab that ran your test is the one that applies to you. Discuss anything that concerns you with your doctor.
