Which of the Five Hepatitis B Antigen-Antibody Tests Being Positive Is Considered Normal?

Generally, it is considered normal if all five hepatitis B tests are negative or only the surface antibody is positive. The former indicates no infection and no antibody presence, while the latter indicates protective antibodies are present. If concerned, it is recommended to consult a doctor in advance. Detailed explanations are as follows:

If all five hepatitis B tests are negative, it indicates that the body has not been infected with the hepatitis B virus nor has it produced protective antibodies. This is considered a healthy state, but it also means there is no immunity against the hepatitis B virus. It is recommended to receive the hepatitis B vaccine promptly to gain protection and reduce the risk of infection.

When only the surface antibody is positive, it usually means the person has either been vaccinated against hepatitis B or has previously been infected and has recovered. This antibody can protect against hepatitis B infection and is considered an ideal normal condition. If the antibody titer is low, consult a doctor to determine if a booster vaccination is needed to enhance protection.

Interpreting hepatitis B test results should involve a comprehensive evaluation of all indicators rather than relying on a single item. If the surface antigen is positive or any other combination other than the two mentioned above appears, timely medical consultation and further testing are advised. After testing, follow professional medical advice, and if necessary, receive vaccination or appropriate treatment.
