Order Hepatitis B Surface Antibody, QuantitativeHepatitis B surface antibody (anti-HBs) is the antibody the immune system produces in response to the hepatitis B surface antigen. A quantitative anti-HBs test measures the concentration of this antibody in the blood and reports it as a numeric value, most often in milli-international units per milliliter (mIU/mL). The result indicates whether a person has measurable immunity to hepatitis B, whether from prior infection that has resolved or from vaccination.
About Hepatitis B Surface Antibody, Quantitative in Berkeley
The quantitative hepatitis B surface antibody test is used to assess immune status against the hepatitis B virus.
The test detects and measures antibodies directed against the hepatitis B surface antigen, the outer protein of the virus. Unlike a qualitative test that reports only positive or negative, a quantitative assay assigns a numeric concentration, which allows the level of antibody to be tracked over time or compared against a defined threshold.
Results are commonly interpreted against a protective threshold. A value at or above the established cutoff generally indicates adequate immunity, while a value below it suggests that antibody levels are low or absent. Interpretation depends on the reason for testing, so results are best reviewed with a clinician who knows the individual's vaccination and infection history.
Hepatitis B surface antibody can be present after a resolved natural infection or after successful vaccination. A quantitative result does not by itself distinguish between these two situations; additional markers such as hepatitis B surface antigen and core antibody may be needed to clarify the clinical picture.
