Blood examination indicated acute liver failure (total bilirubin, 7.8 mg/dL; aspartate aminotransferase, 20 U/L; alanine aminotransferase, 31 U/L; lactate dehydrogenase, 264 U/L; blood urea nitrogen, 2 mg/dL; ammonia, 178 μg/dL; prothrombin percentage activity, 26%; and prothrombin time–international normalized ratio, 2.74). This evidence concerns the gene GPT and acute liver failure.
