I just dicover that my alt and ast levels are high. I may have this problem for last 2 years. I dont drink and no medication used exept alli that in the begining I have used regulary and now less. I have an apt with a doctor in a few days but I am very nervous about hbv. All my othe blood test were normal within the limits and a ct scan for the kidnis and gallblader and the results were good. I do smoke a pak a day. Anybody may think that it can be other reason beside hbv?
