Hi, I am 50 years old. I had blood tests yesterday and here are the abnormal results : creatinine 0.55 mg/dL, AST 57U/L, ALT 165U/L, whereas other liver tests are normal - BILT 0.5, ALB 3.8, TP 6.8. Recently I often take WalPhed PE of Walgreen once I get cold or flu (usually 7-9 days). Is it possibility that the drug causes abnormal results especially ALT like that. I would appreciate your kind reply to my concern.
