Triglyceride Glucose Index (TyG)

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

A recent cross sectional study by Zhang et al. aimed to determine the predictive value of TyG for NAFLD (Fatty Liver Disease). A TyG above 4.6 indicates the possible presence of fat in the liver.
