Hepatitis B I, II and V positive refers to the results of the five hepatitis B tests. One, two and five are hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B core antibody, respectively. A positive core antibody and hepatitis B surface antigen means that the hepatitis B virus is infecting the body because the hepatitis B core antigen is a very strong immunogenic antigen that stimulates the body to produce core antibodies to hepatitis B. This is the fifth item. The hepatitis B surface antigen is a small particle produced by the hepatitis B virus after replication in the body, but this condition is accompanied by a second positive hepatitis B surface antibody, which is not a stable result, because the hepatitis B surface antibody will neutralize the hepatitis B surface antigen, thus becoming a healed state. So in this case, you can improve the relevant tests and regularly review the quantification of the five hepatitis B items to determine which of the hepatitis B surface antigen and the hepatitis B surface antibody will eventually be left.
