What is the HBsAg Test?
The most common test for hepatitis B is the HBsAg test. If
in the test, there is an indication of HBV virus presence in the serum, it will
mean that the infection is present. The test identifies those people who might
be at risk of spreading the disease, like:
- Blood donors
- Pregnant women
- IV drug abusers
- healthcare workers
- Institutionalized people
- Transplant donors
- Recipients
- Semen donors for artificial insemination
For people who are chronically infected, a quantitative HBsAg test is used to monitor their treatment. The screening assays of HBsAg are mostly supported by confirmatory tests. They are then used to confirm repeatable reactive results. In the confirmatory test, the involvement of neutralization of the HBsAg in the sample by >50% using a human anti-HBs antibody is present.
When is it performed?
This test is performed for the following purposes.
- Screening
- Diagnosing HBV infection

What does this test detect?
In this test, the main focus is to look for antigens, antibodies, or the genetic material of HBV. The HBV substances are the Antigens of from the virus that cause your body to produce an immune response. After the immune response, antibodies are produced in response to the virus of HBV.
The main detection will be for Hepatitis B surface antigen (HBsAg): These are various proteins found on the surface of HBV. They can be detected in the test.

IUs. They can also be expressed in signal per cutoff (s/c) value.
Followings are the conditions when the test results will be
positive and negative:
