Results obtained from immunosuppressed patients should be interpreted with caution. Patients receiving mouse antibody therapy may produce false-negative results.
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.
Note: When only a single test, Hepatitis B Surface Antigen, is ordered to diagnose Hepatitis B in a pregnant woman, additional tests such as liver enzymes should be ordered to confirm the diagnosis.
