If possible, you should have hbsag quatitative (in IU/mL) that will tell you weather you are inactive or active hepatitis B.
I would suggest monitor your viral load. With HBV DNA at 2300 IU, you are a "borderline" case between inactive and active hepatitis B especially since your ALT is slightly elevation which could suggest mild hepatitis activity. But then ALT can also rise due to other factors other than hepatitis B. Strenuous exercise, chest workouts and binge alcohol drinking can trigger ALT to go up. If I was you, I would wait another 3-4 months before repeating HBV DNA Viral Load test and ALT. If your viral load is > 2000 IU/L and if ALT is still over 30, I would ask the doctor to start treatment. If your DNA is on the decline naturally and ALT is also close to 30, then you are in true inactive state.
