The increased value of hepatitis B surface antibody quantification refers to the hepatitis B surface antibody. If the test is the quantification of hepatitis B surface antibody or the quantification of the five hepatitis B items, you will be able to determine the current status. If you have previously received the hepatitis B vaccine and are negative for several items other than the hepatitis B surface antibody, it means that the current elevated quantitative hepatitis B surface antibody is due to the previous hepatitis B vaccination. If, in addition to the hepatitis B surface antibody, other items are also elevated, such as the elevated core antibody to hepatitis B, this may be due to the vaccination, but it indicates that the hepatitis B virus was previously acquired.
