Apolipoprotein B (ApoB)
Quick answer
What is Apolipoprotein B (ApoB)?
ApoB counts the number of atherogenic particles in the blood — every LDL, VLDL, and Lp(a) carries one ApoB. Mechanistically the most accurate single lipid read for cardiovascular risk.
- Units:
- g/L
- Reference range:
- <1.0 g/L (general); <0.8 g/L (high CV risk)
- Sample:
- Venous blood (serum)
- Category
- Lipids
- Units
- g/L
- Reference range
- <1.0 g/L (general); <0.8 g/L (high CV risk)
What does a high Apolipoprotein B result mean?
Familial hypercholesterolaemia, insulin resistance, hypothyroidism, ageing. Strongly predictive of cardiovascular events.
What does a low Apolipoprotein B result mean?
Often genetic; sometimes malabsorption.
Why does Apolipoprotein B matter?
ApoB beats LDL-C in current evidence. Most standard panels don't include it; FORM does.
