GPT and tuberculosis: Median AST, ALT, ALP, and TB were also slightly (but significantly) higher in patients with liver metastases compared with those without liver metastases (AST 41 vs 19 U/L; p < 0.001) (ALT 30 vs 21 U/L; p < 0.001) (ALP 123 vs 78 U/L; p < 0.001) (TB 0.4 vs 0.4 mg/dl; p = 0.022).
