The Hepatitis B Test test contains 1 test with 2 biomarkers.
The Hepatitis B test detects acute hepatitis B infections, and can also be used to help diagnose chronic hepatitis B infections. Detecting an early hepatitis B infection is important to avoid health complications. If the HBV test positive returns a positive result for hepatitis B, our labs will automatically run a confirmation test at no additional cost– This ensures that you receive the most sensitive and accurate results.
Hepatitis B Surface Antigen with Reflex Confirmation: Positive samples will be confirmed
Hepatitis B surface antigen (HBsAG) Detects protein that is present on the surface of the virus. It is used to screen for, detect, and help diagnose acute and chronic hepatitis B virus (HBV) infections; earliest routine indicator of acute hepatitis B and frequently identifies infected people before symptoms appear; undetectable in the blood during the recovery period; it is the primary way of identifying those with chronic infections, including "hepatitis B virus (HBV) carrier" state.
Surface antigen usually appears in the serum after an incubation period of 1 to 6 months following exposure to Hepatitis B virus and peaks shortly after onset of symptoms. It typically disappears within 1 to 3 months. Persistence of Hepatitis B surface antigen for greater than 6 months is a prognostic indicator of chronic Hepatitis B infection.
