I checked ALT5 1AST35 73 and 4 days later. I had hepatitis B antibody when I checked two years ago, and I am exercising at this time. Could it be the influence of this?

I think you should check both halves of hepatitis B. If there is no problem, what you said is possible. Poor sleep or colds, as well as other diseases, will lead to a slightly higher ALT value, but your value is only a little higher than normal. If there is no hepatitis B, then I think it is normal.
