Know your ApoB/A1. Know your health.
Test your Apolipoprotein B/A1 Ratio and 100+ other biomarkers in a single blood draw.
Normal range: 0 – 0.77 (lower is better)
The ApoB/ApoA1 ratio captures the balance between atherogenic (harmful) and cardioprotective particles in a single number. Several large studies have found it to be one of the strongest predictors of cardiovascular risk, often outperforming LDL or the standard cholesterol/HDL ratio. A lower ratio means your protective particles are winning the battle against the harmful ones.
A normal ApoB/A1 is 0 – 0.77. Lower is better.
A high ApoB/A1 ratio means too many harmful particles relative to protective ones. The same factors that raise ApoB (poor diet, insulin resistance, genetics) or lower ApoA1 (sedentary lifestyle, smoking, obesity) push this ratio up. Addressing either side improves the balance.
Exercise is uniquely effective here because it both lowers ApoB and raises ApoA1, improving the ratio from both directions. Reducing saturated fat, quitting smoking, losing excess weight, and replacing unhealthy fats with unsaturated fats all help. Statins improve the ratio primarily by lowering the ApoB side.
ApoB/A1 is most highly correlated with Apolipoprotein B and Non-HDL Cholesterol. Here are the top biomarkers correlated with ApoB/A1, based on 500,000 tests done by Empirical Health.
The percentage shows how strongly two biomarkers move together. A higher number means the relationship is stronger. Green = rises and falls together. Orange = one rises as the other falls.
