What does a positive hepatitis B core antibody indicate?

Generally, a positive hepatitis B core antibody indicates a past infection with the hepatitis B virus and that the body has produced corresponding antibodies. However, this alone cannot determine whether there is still an active viral infection. If concerned, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

If the hepatitis B core antibody is positive, the hepatitis B surface antigen is negative, and the hepatitis B surface antibody is positive, it indicates a previous infection with hepatitis B virus and full recovery at present. There is no virus in the body, and protective antibodies have been produced. No special treatment is required, only regular monitoring of antibody levels is needed.

If the hepatitis B core antibody is positive and the hepatitis B surface antigen is positive, regardless of whether the hepatitis B surface antibody is positive or not, it may indicate an ongoing hepatitis B virus infection, with the person being a virus carrier or in the active phase of hepatitis. Further tests, such as viral DNA load and liver function, should be conducted to determine whether treatment is necessary.

Interpretation of a positive hepatitis B core antibody result must be combined with the other four hepatitis B markers; it should not be used alone to make a judgment. After obtaining this result, one should visit a正规 medical institution as soon as possible for a comprehensive evaluation by a qualified physician to avoid delaying treatment due to self-diagnosis.
