Hepatitis B two to half quantitative results, 1, the first thing to look at the hepatitis B surface antigen. If the amount of surface antigen is higher than the normal range of the test, it is positive, which is the state of hepatitis B virus is infecting the human body, it may be a major triplet, a minor triplet, or a minor diyang. If the hepatitis B surface antigen is within the detection range, it is negative and is not an infected state of hepatitis B. 2. Also look at the hepatitis B surface antibody, if the amount of hepatitis B surface antibody is greater than 10mIU/mL, then there is a surface antibody to hepatitis B and there is immunity to the hepatitis B virus. If this value is less than 10mIU/mL, then the hepatitis B surface antibody is negative and there is no immunity to hepatitis B. If at the same time the other four items are also negative, you need to go for hepatitis B vaccination.3. In addition, the last item of the hepatitis B two pairs of half hepatitis B core antibody, if it is positive, indicates that previously infected with the hepatitis B virus. If the other items are negative, you need to check the DNA quantification of hepatitis B to determine whether the current state of hepatitis B infection.
