Table 2 Results of the optimal cut-off values of AST and ALT

From: Defining the optimal cut-off values for liver enzymes in diagnosing blunt liver injury

Cut-off values Sensitivity (%) Specificity (%) PPV (%) NPV (%)
AST ≥ 109 81 82 32 98
ALT ≥ 97 78 88 41 98
AST ≥ 109 and/or ALT ≥ 97 84 81 32 98
  1. LI+ with liver injury, LI− without liver injury, AST aspartate aminotransferase, ALT alanine aminotransferase, PPV positive predictive value, NPV negative predictive value
