Apolipoprotein B/Apolipoprotein A1 Ratio
The ratio of Apolipoprotein B to Apolipoprotein A1 is calculated to assess cardiovascular risk. The ratio reflects the balance between potentially artery-damaging lipoprotein particles and Apo A1 containing HDL particles, and provides a more comprehensive assessment of cardiovascular risk than traditional cholesterol measurements alone, supporting earlier and more targeted interventions.

Common reasons for testing
- Family History of Heart Disease – Assesses inherited risk factors contributing to cardiovascular conditions.
- Monitoring Cholesterol-Lowering Therapy – Tracks the effectiveness of medications or lifestyle changes aimed at reducing cholesterol levels.
- Assessing Risk for Cardiovascular Diseases – Identifies lipid abnormalities that may increase the risk of heart disease or stroke.
