What is the triglyceride:HDL-C Ratio?

The triglyceride:HDL-C (TG:HDL-C) ratio is an important metric of both cardiovascular and metabolic health, and has even been shown to have neurologic implications. It is calculated by dividing your triglyceride level by your HDL-C level.

Why is the TG:HDL-C ratio important?

In recent studies, a high TG:HDL-C ratio has been shown to predict metabolic syndrome, diabetes, and all-cause mortality. In that regard, the ratio provides a good assessment of metabolic health, specifically insulin resistance.

How can I better understand my TG:HDL-C ratio?

Your TG:HDL-C ratio is calculated on a fasting lipid profile. To better interpret your results, here are some values to refer to:

  • Desirable: 1:1 or lower
  • A ratio that’s over 3.5 indicates an elevated risk of cardiovascular events and insulin resistance.

Ranges specific to the Cardiometabolic Program:

  • Optimal: ≤1.0
  • Good: 1.0-1.49
  • Fair: 1.5-2.49
  • Pay attention: >2.50
  • Alert: >5

How can I maintain an optimal TG:HDL-C ratio?

For more information on how to improve your TG:HDL-C ratio, please refer to the triglyceride and/or HDL-C biomarker pages.
