In the immunological examination of hepatitis B virus, the second and fifth of them are positive, that is, positive hepatitis B surface antibody and core antibody, which are mostly seen in the following two cases: the first one is that after the body is infected with hepatitis B virus, due to the low amount of virus or the body’s own immunity is relatively strong, there is no disease, and the surface antibody is passively produced, which is a kind of protective antibody, indicating that the body has acquired the ability to resist The second situation is that the body is infected with the hepatitis B virus. In the second case, the body is infected with the hepatitis B virus and then develops surface antibodies after timely treatment. The fifth positive core antibody here only expresses that the body has been infected with the hepatitis B virus, in short, two positive antibodies is a very good result.
