GPT and cerebral infarction: Ca, K, Cl, TG, high density lipoprotein (HDL), albumin (ALB), globulin (GLO), ALB/GLO, indirect bilirubin (IDBIL), direct bilirubin (DBIL), alanine aminotransferase (ALT), glutamete transpeptidase (GGT), alkaline phosphatase (ALP), polymerase acidic protein (PA), and creatinine (Crea) were found to be significant in distinguishing cerebral infarction in different periods.
