A high hepatitis B virus surface antibody is usually a sign that you have been vaccinated against the hepatitis B virus or have been infected with the hepatitis B virus in the past. The value of Hepatitis B Surface Antibody represents the immunity to Hepatitis B virus, the higher the value, the stronger the resistance to Hepatitis B virus, which can prevent the human body from being infected with Hepatitis B virus. If Hepatitis B surface antibody and Hepatitis B core antibody are positive in Hepatitis B panel, it indicates that you have been infected with Hepatitis B virus in the past, but now the virus has basically been cleared and your body is recovering. If the surface antibody of hepatitis B virus is high, it is usually produced by hepatitis B vaccination, which is a kind of protective antibody and will not jeopardize your health. In order to reduce the infection rate of hepatitis B, China has carried out vaccination of newborns against hepatitis B since 1992, and the vaccination of hepatitis B has been free of charge since 2002. Therefore, people born after 1992 have been vaccinated against Hepatitis B. Therefore, high values of Hepatitis B virus surface antibodies indicate strong immunity against the Hepatitis B virus. However, Hepatitis B antibody does not exist in our body forever, so we need to go to the hospital regularly to recheck the surface antibody of Hepatitis B virus, and if the antibody level decreases or turns negative, we need to make up the Hepatitis B vaccine in time to avoid disease infection.
