GPT and Hyperbilirubinemia: A complete blood cell count was taken, which revealed no abnormality, while the blood chemistry profile demonstrated direct hyperbilirubinemia (total bilirubin, TBIL:20 mg/dl, direct bilirubin, DBIL:16 mg/dl) and a remarkable elevation of the alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGT) (the levels of aspartate transaminase (AST) and alanine transaminase (ALT) were only mildly elevated).
