When to use

Surrogate marker of insulin resistance from routine labs.

How it works

TyG = ln(fasting TG × fasting glucose / 2), mg/dL. Higher values = more insulin resistance.

Key points

  • Derived from a standard lipid/glucose panel.
  • Correlates with cardiometabolic risk.
  • Thresholds are population-specific.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

Fasting triglycerides150 mg/dL
Fasting glucose100 mg/dL

→TyG index8.92

  • Formula：ln(TG × glucose / 2), mg/dL
  • Note：Higher values indicate greater insulin resistance; cut-offs vary by population; there is no single diagnostic cut-off (Simental-Mendía 2008, PMID 19067533).

FAQ

Frequently asked questions

What are the limits and cautions when using Triglyceride-Glucose (TyG) Index?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Triglyceride-Glucose (TyG) Index upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Triglyceride-Glucose (TyG) Index calculated in practice? Can you show a worked example?
Inputs: Fasting triglycerides 150 mg/dL, Fasting glucose 100 mg/dL → Result: TyG index 8.92（Formula: ln(TG × glucose / 2), mg/dL, Note: Higher values indicate greater insulin resistance; cut-offs vary by population; there is no single diagnostic cut-off (Simental-Mendía 2008, PMID 19067533).）
