Triglyceride / HDL Ratio

Measured in ratio

Your triglycerides divided by your HDL — often discussed as an insulin-resistance signal, but it comes from research literature rather than clinical guidelines.

What it is

Triglycerides divided by HDL, often discussed as a rough signal of insulin resistance because the two tend to move in opposite directions as metabolic health shifts. It is genuinely convenient — both numbers are already on a standard lipid panel, so it costs nothing extra. Two cautions matter, though. It is an association rather than a measurement: it does not test insulin, and fasting insulin or an oral glucose test answer that question directly. And its relationship to insulin resistance has been found to vary substantially by ancestry, performing poorly as a signal in some groups, so a given value does not carry the same meaning for everybody. It is a prompt for a conversation, not a diagnosis.

Worth asking your clinician

  • Is the triglyceride/HDL ratio something you find useful, or would you rather look at other markers?
