The main protein on atherogenic lipoproteins; reflects particle number.
What it is
Apolipoprotein B (Apo B) counts atherogenic particles (LDL, VLDL remnants, Lp(a) contribution depending on method).
Why it matters
Increasingly used alongside (or instead of) LDL-C for risk discussion. Clinical targets depend on overall risk.
This guide is educational only and cannot diagnose you. Discuss results, especially anything outside your laboratory’s reference interval, or that does not match how you feel, with a GP or other appropriately qualified clinician.
How it affects the body
Each atherogenic particle carries one Apo B; higher particle number relates to arterial plaque risk over time.
For athletes
Lean athletes can still have genetically high Apo B: lifestyle helps but does not erase inherited risk.
