Hepatitis B Surface Antigen with Reflex Confirmation: Positive samples will be confirmed
IMPORTANT: NOTE THIS IS A REFLUX TEST - The price charged for this test is only for the Hepatitis B Surface Antigen. ADDITIONAL CHARGE OF $39 WILL OCCUR FOR THE REFLUX CONFIRMATION if the Hepatitis B Surface Antigen is positive.
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.
Clinical Significance
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.
