The Hepatitis B Surface Antigen (HBsAg) - Confirmation (Neutralisation Test) is crucial in detecting and confirming the presence of the hepatitis B virus in your body.

HBsAg is the first marker that appears in the blood following infection with hepatitis B. Its presence means a person is infectious and can spread the virus to others. A confirmatory test is essential to avoid false positives, which can occur due to various reasons, such as the presence of certain substances in the blood. The neutralisation test is a type of confirmation test for Hepatitis B, used to ascertain whether an initially positive result for HBsAg is indeed true.
