🩸 Triglyceride-Glucose (TyG) Index
Estimate insulin resistance with the triglyceride-glucose (TyG) index.
Triglyceride-Glucose (TyG) Index
Fasting triglycerides (mg/dL)
Fasting glucose (mg/dL)
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.
