Normal people’s hepatitis B penta results will show three kinds of results, one is simple surface antibody positive, the second is all hepatitis B penta negative, and the third is double antibody positive. 1. Positive simple surface antibody: in this case, it means that the human body has been vaccinated against hepatitis B, and the body has produced protective antibody, which has certain immunity against hepatitis B virus. 2. Hepatitis B five negative: in this case, it means that the human body has not been infected with hepatitis B virus, but it is also not resistant to hepatitis B virus and lacks protective antibodies, so it is easy to be infected by hepatitis B virus. 3. Double antibody positive: surface antibody positive, core antibody positive or e antibody positive, indicating that the human body has been infected with hepatitis B virus before, but now the virus has been cleared, and the human body has produced protective antibodies and has certain immunity. To summarize, patients who are purely positive for surface antibody and double antibody have a low chance of being infected with hepatitis B virus again, and the body has protective antibody; patients who are negative for all five items of hepatitis B need to go to the regular vaccination center in time to receive hepatitis B vaccine.
