Hepatitis virus (Hepatitis B virus) surface antibody greater than 10000mIU/ml is normal, usually regular rechecking can be done, no special treatment is needed. Hepatitis B surface antibody is produced by the surface antigen of hepatitis B virus to stimulate the immune system of human body, it is a kind of protective antibody, which can neutralize the hepatitis B virus and prevent the body from being infected by the virus. Hepatitis B surface antibody quantitative >10000mIU/ml means strong immunity against hepatitis B. The normal value of Hepatitis B surface antibody quantitative is 10, more than 10 means that Hepatitis B surface antibody is positive, immune to Hepatitis B virus, able to resist Hepatitis B virus infection, and 10000mIU/ml titer is extremely great, in this case the immunity against Hepatitis B is very strong. It is usually produced in healthy humans after hepatitis B vaccination. Theoretically, the higher the antibody titer, the better the protection. Generally speaking, the antibody titers of people who have just completed the injection are high, and then they will gradually decline with the passage of time, and their effective titers can be maintained for about 8 to 10 years. As long as the surface antibody titer is maintained above 10, it is protective, if it is lower than 10, a booster shot of hepatitis B vaccine can be given. If there is any discomfort, you should consult a doctor in time.
