GPT and liver failure: Initial blood tests (normal values range in parenthesis) revealed a total bilirubin level of 12.7 (0.3–1.5) mg/dL, direct bilirubin of 7.2 (0.1–0.5) mg/dL, alanine aminotransferase (ALT) of 973 (17–63) IU/L, aspartate transaminase (AST) of 867 (15–41) IU/L, alkaline phosphatase (AP) of 96 (38–126) IU/L, and an INR of 1.9 (0.8–1.2) clearly suggestive of mild hepatic failure with a hepatocellular pattern of injury.
