Hi. I recently had a series of blood test due to a higher than average results on my AST (ie: 52) and ALT (ie: 71). I also did a CT scan which came out good. All other tests were also good even after the series of blood test. It's the AST & ALT that's been really problematic. I don't drink, no drugs, eat healthy, drinks water a lot and works out at least 5x a week. What else can be causing it? Anything to worry about? What other tests do you suggest I take? What signs should I be looking for? Any help you can extend is greatly appreciated.
