SEROLOGY
Australia Antigen (HbsAg)
NON-REACTIVE
Comment
NOTE : - TO BE CONFIRMED BY ELISA OR OTHER METHOD.
HBsAg is the surface antigen of the hepatitis B virus (HBV). It indicates current hepatitis B infection.
These antigen-proteins can be genetically manufactured (e.g. transgene E. coli) to produce material for a simple antigen test, which detects the presence of HBV. It is present in the sera of patients with viral hepatitis B (with or without clinical symptoms). Patients who developed antibodies against HBsAg (anti-HBsAg seroconversion) are usually considered non-infectious. HBsAg detection by immunoassay is used in blood screening, to establish a diagnosis of hepatitis B infection in the clinical setting (in combination with other disease markers) and to monitor antiviral treatment. Positive HBsAg tests can be due to recent vaccination against Hepatitis B virus but this positivity is unlikely to persist beyond 14 days post-vaccination
