Cholesterol Ratio Calculator
Cholesterol ratios provide a more comprehensive picture of cardiovascular risk than individual cholesterol numbers alone. Enter your lipid panel results to calculate key ratios and receive a risk assessment based on American Heart Association guidelines.
While individual cholesterol values are important, ratios between different lipid components are stronger predictors of heart disease risk. The Total Cholesterol/HDL ratio is the most widely used: a ratio below 3.5 is considered optimal, while a ratio above 5.0 indicates elevated cardiovascular risk. The LDL/HDL ratio measures the balance between "bad" and "good" cholesterol, with values below 2.0 considered optimal. The Triglyceride/HDL ratio has emerged as a valuable marker for insulin resistance and metabolic syndrome, with values above 4.0 suggesting increased risk.
HDL cholesterol is protective because it helps remove LDL cholesterol from arteries. Desirable levels are above 40 mg/dL for men and above 50 mg/dL for women, with values above 60 mg/dL providing additional protection. LDL cholesterol below 100 mg/dL is optimal; above 160 mg/dL is considered high. Total cholesterol below 200 mg/dL is desirable, and triglycerides below 150 mg/dL are normal.
