Elevated Liver Enzymes

I have Crohns disease which is under good control using Imuran (on it for one and a half years) and remicade (on it for a year). I have always had normal liver enzyme tests. However i recently got a test back with my AST at 514 and my ALT at 170. My ALK Phosphate was 159. My bilirbin was normal as was my albumin and total protein.

Could this elevation be due to over excercising? or are levels not seen that high traditionally from muscle damage or injury?

Also, if bilirubin is normal, is it less likely that the increase in the AST is due to some viral disease such as hepatitis b/c?

Could it be a false positive or is that unusual?

thanks
