Hepatitis B surface antigen HBsAg quantification is less than 0.05 IU/ml, which is the normal value, or negative result. Hepatitis B virus surface antigen HBsAg is a serologic marker of HBV infection, and the presence of HBsAg persisting for more than 6 months implies chronic infection. Hepatitis B virus core antigen (HBcAg), on the other hand, is an intracellular antigen expressed in infected hepatocytes and is not detectable in serum. Hepatitis B virus core antibody (anti-HBc) is detectable throughout the course of HBV infection. Hepatitis B e antigen (HBeAg) is a secreted protein processed from pre-core proteins and is generally considered to be a marker of HBV replication and infectivity. If you are infected with the hepatitis B virus, you should go to the hospital for treatment and take medication under the guidance of a physician to avoid delays.
