Hepatitis B Surface Antibody Immunity, Quantitative Test
This test measures the concentration of antibodies against the Hepatitis B virus surface antigen, reported as a quantitative value. Quest describes it as used to assess immune status following vaccination or infection, based on CDC guidelines.
About this test
Hepatitis B surface antibody develops after a successful immune response to Hepatitis B vaccination, or after recovering from infection. This quantitative version reports the antibody amount as a value rather than only a positive or negative result, which Quest describes as used to determine immune status per CDC guidelines.
The test uses a 1 mL serum sample, analyzed by immunoassay. Quest lists it under the name Hepatitis B Surface Antibody Immunity, Quantitative, reflecting that it is a numeric measure of antibody level rather than a simple detected/not detected result.
Who might consider this test?
- Because the result is a quantitative value, a clinician reads it against CDC guidance for what counts as an immune level.
