TyG Index Calculator

The triglyceride and glucose index is a screening method for insulin resistance that is very simple to use and only requires two laboratory determinations: serum triglycerides and serum glucose.

According to a study by Salazar et al. insulin resistance cut off is placed at the TyG index value of 4.49, with a sensitivity of 82.6% and specificity of 82.1% (AUC=0.889, 95% CI: 0.854-0.924)

Subjects with an index of 4.49 or greater are likely to suffer from insulin resistance.

TyG equation:

TyG = ln [Fasting triglyceride (mg / dl) x Fasting glucose (mg / dl)] / 2
