Initial laboratory studies revealed significant elevation of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (AST 2222 IU/L, ALT 432 IU/L), creatinine (Cr) of 2.29 mg/dL, hypocalcemia (ionized calcium of 0.92 mmol/L), hyponatremia (127 mmol/L), and a moderately increased high-sensitivity troponin level (HST) of 102 pg/mL. Here, GPT is linked to Hyponatremia.
