Your question was already answered on Aug 23rd. The answers won't change no matter how many times you ask the same question. Take the advice that was given at that time please. Hopefully you will get some advice on the Liver Disease forum. In the end only a doctor can diagnose and treat your son. We are not doctors here. We are people who have been affected by hepatitis C here and are not experienced with all liver diseases or other types of disease. Perhaps it would be better to focus your concern for answers on the medical specialists that know the true status of your sons health.
Good luck.
Regards.

Hi - I am sorry you and your son are struggling. Your ALT/AST can be elevated for a number of reasons not limited to Hepatitis. Since you know your son is negative for Hepatitis, I urge you to find the right venue for your questions. Someone here may have experience with CPK but I hope you find appropriate medical care if you don't already. There are tests they can do and they should be able to give you answers - they must -or find someone better. Sometimes you really have to fight for good care.
Good luck and hope it all works out for you both.
