About this biomarker
Apolipoprotein B, or ApoB, reflects the number of atherogenic lipoprotein particles in the blood. It can add detail beyond standard cholesterol values.
Why it matters
It helps estimate the burden of particles that can contribute to plaque buildup.
What lower levels may suggest
Low ApoB usually reflects fewer atherogenic lipoprotein particles.
What higher levels may suggest
High ApoB suggests a higher number of cholesterol-carrying particles associated with cardiovascular risk.
