[|Human|] Good morning Dr. Grief,I donated my blood in December. Yesterday, I got mail and found down that I had Hepatitis B positive. However, they run another test the HBsAg and HBV Nucleic Acid Test were negative. I am really worried, Is there any medicine I need to take to kill the virus. Please help
[|AI|]  You do not need to take any medicine to kill the virus. You do not have the virus now. Furthermore, you may have had it in the past, but your body fought it off. The Bag and HBV nucleic acid test both test specifically for the virus, and yours were negative. The other was most likely an antibody test. That indicates prior exposure and will always be positive. It will also be positive if you had the immunization for hepatitis B. So no need to worry. You do not have the virus now. Hope this helps.
