What it is

Apolipoprotein B counts the particles that build plaque, one ApoB per particle. Many lipid specialists trust it most, and it can be high even when LDL looks fine.

How to read the lab range

Under 90 mg/dL is commonly quoted as good and lower for people with other risk factors; above 130 is commonly read like a high LDL.

Questions people ask

LDL is fine but ApoB is high, which is right?

They measure different things. ApoB counts particles; LDL measures cholesterol mass. Many small particles can mean a high ApoB with a normal LDL, which is worth raising with your doctor.
