Probably: If your hepatitis b surface antibody is positive and surface antigen negative with non-detectable viral load. It means you have s antigen seroconversion with medication, which is an excellent response. After you achieve that, continue Baraclude (entecavir) for about 12 months or so then you can stop baraclude (entecavir).

Infected or vaccine?: Probably your partner had a blood test showing antibody to the hepatitis B virus (HBV), i.e. anti-HBs and/or anti-HBc. It means one of two things: either he was vaccinated against hep B; or he was infected and his immune system cleared it up. The details (anti-HBs or HBc) can help tell. If he was infected, the blood test says nothing about how he caught it. If you feel you need to know, ask him! ...Read more
