So my father ages 60 years and have an elevated ALT/SGPT which is 106 U/L and also high level of AST/SGOT which is 99 U/L. The alkaline phosphate, serum is also high, 171 U/L. My father doesn't drink at all. His height is 5'11" and he weights 80 kg. I am very worried about his health! He has some skin issues for which medication is going on. Is this higher than normal level very critical ? What next should I do?
