Patient's question:
All symptoms My boyfriend has hepatitis B surface antigen positive, and we had sex again. Now I have gone for a checkup and found that my hepatitis B surface antibody is positive, while others 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 exposed to the virus in the past and has developed 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.
