Is treatment required for a positive HBsAb result?

Generally, a positive HBsAb result does not require treatment, as it usually indicates the presence of antibodies against the hepatitis B virus in the body. If concerns persist, it is recommended to seek medical advice in advance. Detailed explanation is as follows:

HBsAb, or hepatitis B surface antibody, is a protective antibody. This antibody is produced in the body after receiving the hepatitis B vaccine or following recovery from a previous hepatitis B virus infection. It effectively protects against hepatitis B virus infection. A positive result in this case is normal and beneficial and does not require any special management.

If a positive HBsAb result is accompanied by a positive hepatitis B surface antigen, it may indicate the recovery phase of hepatitis B infection or a special infection status. In such cases, comprehensive judgment based on other test results is necessary. However, a positive HBsAb alone is not an indicator of disease and does not fall into the category requiring treatment.

Individuals with a positive HBsAb result can periodically check their antibody titers. If the titer is too low, a booster dose can be administered under a doctor's guidance to maintain effective protection. There is no need to self-medicate solely based on a positive HBsAb result.
