Median liver enzyme levels were slightly (but significantly) higher in patients with liver metastases compared with those without liver metastases (AST 36 vs 21 U/L; p < 0.001) (ALT 26 vs 24 U/L; p = 0.018) (ALP 135 vs 94 U/L; p < 0.001) but not for TB (0.5 vs 0.4 mg/dl; p > 0.05). The gene discussed is GPT; the disease is tuberculosis.
