This is the gold-standard, advanced assessment of your heart disease risk. It goes beyond a simple cholesterol test. It measures the ratio of Apolipoprotein B (the main 'bad' cholesterol carrier) to Apolipoprotein A1 (the main 'good' carrier). This Apo B/Apo A1 ratio is considered by many experts to be the most accurate predictor of cardiovascular risk, even more so than standard LDL/HDL levels. A simple blood test is required. Don't just know your cholesterol; know your true risk. This is the next level of proactive heart health.
