Triglyceride-Glucose (TyG) index
Triglyceride-glucose (TyG) index, a surrogate of insulin resistance from fasting triglycerides and glucose (mg/dL).

Example
- Fasting triglycerides
- 150 mg/dL
- Fasting glucose
- 100 mg/dL
Result: TyG index 8.92 (triglycerides 150 mg/dL, glucose 100 mg/dL). Higher values indicate greater insulin resistance; no universal diagnostic cut-point.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Lower
- Lower TyG indicates greater insulin sensitivity.
- Higher
- Higher TyG indicates greater insulin resistance; no universal diagnostic cut-point.
What you enter
- Fasting triglycerides
- Fasting glucose
