What Is a Hepatitis B Titer?

A titer is a way of expressing concentration. A hepatitis B titer generally refers to the measurement of the two blood tests, Hepatitis B Surface Antibody (anti-HBs or HBsAb) and Hepatitis B Surface Antigen (HBsAg).

If you wish to know whether the vaccine is effective, you can have your anti-HBs titers checked following the last shot of the hepatitis B vaccine series. If your titer is greater than 10 mIU/mL, it means you have adequate immunity to hepatitis B virus.
