Hepatitis B core antibody is positive Surface antibody is positive generally do not need to take booster shots, but also need to analyze the specific problems. Positive hepatitis B core and surface antibodies usually indicate that the body has been infected with the hepatitis B virus before, but under the action of the immune system, it has cleared the virus and restored its health, and produces protective antibodies, which give the body a certain resistance to be re-infected by the hepatitis B virus. The ability of Hepatitis B surface antibody to resist the Hepatitis B virus is related to the antibody titer. In the test result, if the titer of hepatitis B surface antibody is high, the ability to resist hepatitis B virus is stronger. If the titer is low, the ability to fight off the virus decreases over time, so a booster shot is needed. After the patient is positive for hepatitis B core antibody and surface antibody, he/she needs to check the liver function and hepatitis B DNA regularly, if there is any abnormality, consult the doctor in time and treat according to the doctor’s advice.
