Blood tests showed an elevated white blood cell count (13,400/μL; neutrophils, 85.5%), elevated C-reactive protein (21.5 mg/dL), elevated aspartate aminotransferase (AST, 56 U/L), alanine aminotransferase (ALT, 47 U/L), and lactate dehydrogenase (LDH, 388 U/L), as well as hyponatremia (132 mmol/L). Here, GPT is linked to Hyponatremia.
