Hepatitis B surface antibody greater than 100 IU/mL is normal.
Hepatitis B surface antibody greater than 100IU/mL means that there are protective antibodies against hepatitis B in the body, which can prevent infection by hepatitis B virus. Hepatitis B surface antibody can be increased if you have been vaccinated against Hepatitis B or if you have been infected with the Hepatitis B virus and have produced antibodies after clearing the virus due to a strong autoimmune system.
Hepatitis B surface antibody less than 10IU/mL is negative, more than 10IU/mL is positive, between 10~60IU/mL is weak positive, the antibody titer is not enough, this time need to take a shot of hepatitis B vaccine to strengthen, more than 60IU/mL generally means that the antibody concentration is enough.
If only the surface antibody of hepatitis B is increased and the rest of the items are not abnormal, then the result is normal, and regular recheck can be done. If the rest of the items are abnormal, it is recommended to consult a specialist in the hospital for further examination if necessary.
