What It Measures
The number of atherogenic lipoprotein particles in the blood. Each particle has exactly one ApoB molecule, so ApoB directly reflects particle count.
ApoB is a protein found on every atherogenic lipoprotein particle (LDL, VLDL, IDL, Lp(a)). It is considered the single best predictor of cardiovascular risk — better than LDL-C alone.
Current Value
What High Means
Elevated ApoB means more atherogenic particles in circulation, significantly increasing risk of plaque buildup, heart attack, and stroke — even if LDL-C appears normal.
Possible Symptoms
No direct symptoms; damage accumulates silently over decades
What Low Means
Low ApoB is protective and indicates fewer atherogenic particles. It is one of the strongest indicators of low cardiovascular risk.
Possible Symptoms
None; indicates cardiovascular protection
Risk Factors
Atherosclerosis, coronary artery disease, heart attack, stroke

Diet & Lifestyle
- •Prioritize ApoB over LDL-C for risk assessment
- •Reduce saturated fat if ApoB is elevated
- •Regular aerobic exercise
- •Consider statin or PCSK9 therapy if ApoB remains high
- •Get advanced lipid testing periodically
