Hepatitis B Surface Antibody, Qualitative Test
This test checks for hepatitis B surface antibody (anti-HBs) in a serum sample using immunoassay. Quest describes a detected result as indicating prior immunologic exposure to the hepatitis B antigen or vaccine.
About this test
Hepatitis B surface antibody, qualitative, reports whether this antibody is detected in serum, rather than giving a numeric antibody level. Quest describes a positive result as indicating prior immunologic exposure to the hepatitis B antigen or the hepatitis B vaccine.
The test uses a 1 mL serum sample, analyzed by immunoassay. Because the result is reported as detected or not detected rather than as a value, it answers whether antibody is present without measuring how much.
Who might consider this test?
- A clinician reads the result together with vaccination and exposure history.
