Hepatitis B 245 positive is defined as positive hepatitis B surface antibody, positive hepatitis B e antibody, and positive hepatitis B core antibody. A positive hepatitis B surface antibody indicates that there are protective antibodies in the body. There is immunity to the hepatitis B virus. A positive hepatitis B e antibody also indicates a previous infection with the hepatitis B virus, but now there is some immunity to the hepatitis B virus and the hepatitis B virus is no longer replicating. If you have a positive core antibody, you have been infected with the hepatitis B virus in the past and the core antibody will persist for many years because of the long half-life of the hepatitis B core antibody. 3 positive antibodies indicate a history of acute hepatitis B and chronic hepatitis B. At present, the hepatitis B virus has been cleared and is not contagious, the hepatitis B is in a state of recovery and the body has immunity, in which case you also need regular checkups. If the hepatitis B virus is still in the normal range, it means that hepatitis B has been cured.
