Diagnosis of acute, recent, or chronic hepatitis B infection.
Determination of chronic hepatitis B infection status.
This test is not offered as a screening or confirmatory test for blood donor samples.
This test, by itself, is not useful during the “time window” of acute hepatitis B virus (HBV) infection (i.e., after hepatitis B surface antigen disappears and before the appearance of hepatitis B surface antibody). Testing for acute HBV infection should also include hepatitis B core IgM antibody (IgM anti-HBc).
