1, HBsAg hepatitis B virus surface antigen, also formerly known as HAA, is the shell protein of the hepatitis B virus, which is not infectious in itself and therefore should not be used as a marker of infectiousness. HBsAg only indicates that there has been or is an infection with the hepatitis B virus. This alone does not indicate whether the hepatitis B virus is still replicating at the moment. 2, HBsAb hepatitis B virus surface antibody, also known as anti-HBs, is a protective antibody, is a sign of immunity after infection with the hepatitis B virus. It is a symbol of hepatitis B cure or tend to cure. 3, HBeAge antigen, HBcAg core antigen, HBV-DNA, are structural components of the core of the hepatitis B virus, their presence indicates that the presence and replication of the hepatitis B virus is still present in the blood. 4, HBeAbe antibodies, also known as anti-HBe,, positive indicates that the hepatitis B virus replication is not active, is a sign that the hepatitis B virus has been infected for a relatively long time. However, if the HBV-DNA is positive, it means that the hepatitis B virus is still present in the blood or the virus has mutated. 5, HBcAb core antibody, also known as anti-HBc, its main component is the IgG type in the core antibody. Positive is a sign of previous or current infection with hepatitis B virus. As with HBsAg, this alone does not indicate whether the hepatitis B virus is reproducing or not. “Usually, we use different combinations of the two halves to determine the status and regression of hepatitis B infection. This indicates a late latent phase of acute hepatitis B virus infection; 2. The fifth positive item and the remaining four negative items. It means it is a recessive carrier of hepatitis B virus or in the window period of infection, also means it has been infected with hepatitis B virus; 3, the first three positive, the remaining three negative. It indicates the early stage of acute hepatitis B; 4. The first, five positive, the remaining three negative. It means acute and chronic hepatitis B; 5. First, three, five positive, the remaining two negative. Commonly known as “major triplet”, this situation indicates acute and chronic hepatitis B; 6, the first, fourth, five positive, the remaining two negative. Commonly known as “small triple”, indicating acute and chronic hepatitis B; 7, the fourth, five positive, the remaining three negative. It means that the person is recovering from acute hepatitis B virus infection or has been infected with hepatitis B virus; 8. The second, fourth and fifth items are positive and the remaining two are negative. Indicates a recovery period of hepatitis B, with existing immunity; 9. Second, five positive, the remaining three negative. It means that the person has recovered from hepatitis B vaccination or hepatitis B virus infection and has immunity.
