This is your single most powerful number for understanding heart disease risk. The Total Cholesterol to HDL Ratio is a calculation we provide as part of your Lipid Profile. It compares your total cholesterol to your good (HDL) cholesterol. A lower ratio is ideal, as it means you have more "good" cholesterol in proportion to the total. This ratio is often a more accurate predictor of your risk than any single number alone. Don't just look at individual numbers. This powerful ratio provides the true, actionable insight into your cardiovascular health.
