Normal liver function and positive hepatitis B antibody means that you have been infected with hepatitis B virus, but now you are in the state of recovery, not in the state of infection. After hepatitis B virus infection, it can produce many kinds of antigens in the body, such as HBsAg (hepatitis B surface antigen), hepatitis B core antigen (HBcAg), hepatitis B e antigen (HBeAg), and each kind of antigen has corresponding antibodies, such as hepatitis B surface antibody (anti-HBs), hepatitis B e antibody (anti-HBe), hepatitis B core antibody (anti-HBc). Hepatitis B surface antibody is a protective antibody, and being positive means that you are immune to the hepatitis B virus. Some people who have recovered from hepatitis B infection and those who have been vaccinated against hepatitis B can show positive hepatitis B surface antibody. Hepatitis B e antibody and Hepatitis B core antibody appear after infection with the Hepatitis B virus and can be present for a long time. When all three hepatitis B antibodies are positive and liver function is normal, it is mostly considered that people who have been infected with hepatitis B are now in a state of recovery and are not contagious, and it is recommended that they should have regular checkups, and if they feel unwell, they should consult a doctor in time.
