HBsAg confirmatory assay3000-1090 10 testsFor the confirmation of the presence of hepatitis B surfaceantigen in human serum or plasma found to be reactivewith the bioelisa HBsAg 3.0 assay.SummaryHepatitis B is a disease produced by a viral infection during which many serological markersappear. One of these markers is HBsAg. The presence of HBsAg in serum or plasma constitutesthe most important indicator for the diagnosis of a hepatitis B virus (HBV) infection. A repeatedlypositive result for HBsAg is indicative of a hepatitis B virus infection. bioelisa HBsAgconfirmatory assay uses the principle of specific antibody neutralization to confirm the presenceof HBsAg in human serum or plasma repeatedly reactive with the bioelisa HBsAg 3.0 assay.
