Patient's question:
All symptoms My boyfriend has hepatitis B surface antigen positive, and we had sex again. Now I've gone for a checkup and found that my hepatitis B surface antibody is positive, while other tests are negative. Is there a problem?Doctor's answer:
A positive hepatitis B surface antibody indicates that you have been exposed to the hepatitis B virus or have received the hepatitis B vaccine, which has stimulated your immune system to produce antibodies. This is good. It has a titer level, and the titer decreases over time. This is why it is necessary to get the hepatitis B vaccine booster at regular intervals. When this test result is negative, you need to get the vaccine to stimulate antibody production. This is not a problem. It proves that your boyfriend has previously received the hepatitis B vaccine and has developed antibodies. Alternatively, he may have been previously infected with the hepatitis B virus and now has antibodies, meaning he can no longer be infected and serves as a protective barrier, ensuring he will not transmit the virus to others. Rest assured.
