Significance of test

The hepatitis B Virus causes viral hepatitis.. 1-5% infected people act as chronic carriers of Hepatitis B virus.. Major part of the chronic carriers secrete hepatitis B surface antigen (HBsAg) into the blood and other secretions of the body like saliva and vaginal fluid. These chronic carriers are potentially infectious to other seronegative people. Hepatitis B Virus belongs to a family of enveloped DNA virus, the Hepadnavirus. Related viruses in this group cause chronic hepatitis. HBsAg has been accepted as a universal and the most reliable seromarker in case of acute HBV infection due to its appearance almost 2-4 weeks before the ALT level becomes abnormal and 3-5 weeks before the onset of symptoms or jaundice as an early detection system for hepatitis infection. In most cases of HBV infection, the incubation period varies from 40 days to 6 months.
