ApoB/ApoA1 Ratio
Formula
ApoB / ApoA1What It Reveals
Balance between atherogenic and protective lipoproteins.
Interpretation Ranges
Optimal
< 0.6
Favorable lipoprotein balance
Borderline
0.6–0.8
Moderate cardiovascular risk
High Risk
> 0.8
Unfavorable — high atherogenic particle load
Clinical Significance
The ApoB/ApoA1 ratio integrates both harmful (ApoB-containing) and protective (ApoA1/HDL) particles into a single metric. Large studies (INTERHEART) found it superior to standard lipid ratios.
What To Do
Lower ApoB through diet, statins, or PCSK9 inhibitors. Raise ApoA1 through exercise, moderate alcohol, and omega-3s.
