A positive hepatitis B test 245 means positive hepatitis B surface antibody, positive E antibody and positive core antibody, indicating previous infection with hepatitis B virus. If the transaminases are normal and the hepatitis B virus DNA is negative it means that the patient is currently in the recovery stage, but it does not mean that he is immune for life. Because hepatitis B virus may be present in the nucleus of hepatocytes, it may cause reactivation of hepatitis B virus in patients treated with chemotherapeutic drugs or immunosuppressive agents, and hepatitis B virus DNA positivity appears as hepatitis activity. In addition, a hepatitis B virus DNA test should be done for those who are 245 positive to rule out occult hepatitis.
