ApoB/ApoA1 Ratio

The ApoB/ApoA1 ratio compares the number of potentially atherogenic particles (ApoB) to protective HDL particles (ApoA1). It is considered one of the strongest predictors of cardiovascular risk, potentially superior to traditional lipid ratios. A lower ratio indicates a more favorable balance between "bad" and "good" particles. Optimal ratios are generally <0.7, with higher ratios indicating progressively increased cardiovascular risk.
