Hepatitis B two halves usually do not exist when they are all positive, because two halves refer to antigen and antibody, respectively, and pairs of antigen and antibody are generally not mutually exclusive, and there will be no antibody if there is antigen, and there will be no antigen if there is antibody. Only when the antigen gradually turns negative and the antibody gradually turns positive can such a manifestation occur. For example, if hepatitis B surface antigen and surface antibody exist at the same time, it is usually the case that the antibody is on the way up and the antigen hasn’t dropped to normal yet, so when this happens, you should have a reexamination after a period of time, and usually the antibody will turn positive and the antigen will turn negative. Hepatitis B e-antigen and e-antibody are also like this, usually appearing when Hepatitis B major triple positive is transformed to Hepatitis B minor triple positive. However, it is very rare for hepatitis B surface antigen and antibodies to be positive at the same time as hepatitis B e antigen and antibodies. If this is the case, it is likely that the test was qualitative Hepatitis B Penta and it is recommended that the test be quantitative Hepatitis B Penta, and it is possible that this will no longer be the case. Even if this is the case, the quantitative test should be done because the quantitative test can dynamically observe the trend of each item, so as to determine in what direction it will change in the future.
