Laboratory investigations showed leukopenia (white blood cell (WBC) of 3.9 × 109/L), elevated transaminases (alanine transaminase (ALT) of 202 IU/L and serum aspartate aminotransferase (AST) of 158 IU/L), and mildly raised bilirubin levels (total bilirubin of 5.8 μmol/L, direct bilirubin of 2.8 μmol/L). Here, GPT is linked to Decreased total leukocyte count.
