Reference cutoffs
- Total/HDL: under 3.5 optimal, over 5 elevated
- Triglycerides/HDL: under 2 optimal, over 4 elevated
- Non-HDL: under 130 optimal, 160+ elevated
- HDL: aim above 40 (men) or 50 (women)
Ratios are stronger predictors of cardiovascular risk than any single number. The triglyceride-to-HDL ratio is a rough proxy for insulin resistance. Discuss with your clinician, especially if you have diabetes or family history of heart disease.
About
Enter the four numbers from your lipid panel. The tool calculates the ratios that better predict cardiovascular risk than any single value, with reference cutoffs.
How to use
- Enter total cholesterol and HDL.
- Enter LDL and triglycerides.
- Read the ratios.
FAQ
Why ratios over single numbers?+
Total cholesterol alone hides the protective effect of HDL. The total/HDL ratio is more predictive of heart disease in most populations.
What's the trig/HDL ratio for?+
It's a rough proxy for insulin resistance. Below 2 is good, above 4 suggests metabolic issues worth discussing with a clinician.
