Rapid test for the qualitative detection of Hepatitis B surface antigen (HbsAg) in whole blood, serum or plasma. The Hepatitis B – HBsAg Cassette Rapid Test Cassette is a rapid test for the qualitative detection of the presence of HBsAg in whole blood, serum or plasma samples. The test uses a combination of monoclonal and polyclonal antibodies to selectively detect high levels of HBsAg in whole blood, serum or plasma. Viral hepatitis is a systemic disease that primarily involves the liver. Most cases of acute viral hepatitis are caused by hepatitis A virus, hepatitis B virus (HBV) or hepatitis C virus. The complex antigen found on the surface of HBV is called HbsAg. Previous designations include the Australia or Au antigen.1 The presence of HBsAg in whole blood, serum or plasma indicates both acute and chronic active hepatitis B infection. In a typical hepatitis B infection, HBsAg is detectable 2 to 4 weeks before the ALT level becomes abnormal and 3 to 5 weeks before symptoms or jaundice develop. HBsAg has four main subtypes: adw, ayw, adr, and ayr. Due to the antigenic heterogeneity of the determinant, there are 10 major serotypes of the hepatitis B virus. The HBsAg Cassette Rapid Test Cassette is a rapid test for the qualitative detection of the presence of HBsAg in whole blood, serum or plasma samples. The test uses a combination of monoclonal and polyclonal antibodies to selectively detect high levels of HBsAg in whole blood, serum or plasma. The HBsAg Rapid Cassette Test is a qualitative immunoassay using the two-site sandwich method for the detection of solid phase HBsAg in whole blood, serum or plasma. The membrane is pre-coated with anti-HBsAg antibodies near the test line on the cassette. During the test, the whole blood sample, serum or plasma, reacts with the particles coated with anti-HBsAg antibodies. The mixture migrates upward on the membrane chromatographically by capillary action to react with the anti HBsAg antibodies on the membrane and thus generate a colored line. The presence of the colored line in the test region indicates a positive result, while its absence indicates a negative result. With the procedural control function, on the control area, a colored line will appear to indicate that the right amount of sample has been added and that membrane transpiration has occurred.
