Hepatitis B core antibody positive +, may be now being infected with the virus, or may be previously infected with the virus, need to be combined with other indicators of hepatitis B five to make a comprehensive judgment. 1. Currently infected with the virus: if the hepatitis B core antibody is positive +, and at the same time, the hepatitis B surface antigen and e antigen are positive, this is called hepatitis B triple positive, which indicates that the hepatitis B virus is replicating now, and it is a current infection. 2. Previously infected virus: if only hepatitis B core antibody is positive +, the other four items (hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B E antigen, hepatitis B E antibody) are negative, this is most likely to have been infected with hepatitis B virus in the past, and now it has entered into the recovery period, and at this time, no hepatitis B protective antibody has been produced, so it is necessary to inject hepatitis B vaccine in time. If the hepatitis B core antibody is positive +, hepatitis B surface antigen is positive, it is recommended to go to the hospital in time to complete the appropriate tests, such as hepatitis B virus DNA quantitative, liver function tests, etc., and listen to the doctor’s advice, choose the appropriate method to deal with.
