Apolipoprotein B
What It Is
Apolipoprotein B is a protein found on LDL and other atherogenic lipoprotein particles.
Why It Matters
Apo B is considered a more accurate predictor of cardiovascular risk than LDL cholesterol alone, as it counts every atherogenic particle.
If Levels Are High
Elevated Apo B indicates a higher number of atherogenic particles and increased cardiovascular risk.
If Levels Are Low
Low Apo B suggests fewer atherogenic particles and is generally favourable.
Preparation
Fasting for 10–12 hours is recommended.
How Often to Test
Annually, or more often if managing cardiovascular risk.
