Description

The HBsAG Rapid Test Cassette is a rapid chromatographic immunoassay fort the qualitative detection of Hepatitis B Surface Antigen in serum or plasma.

Principle

The HBsAG Rapid Test Cassette is a quantitative, solid phase, two-sirte sandwich immunoassay for the detection of HbsAg in serum or plasma. The membrane is pre-coated with anti-HbsAg antibodies on the test line region of the cassette. During testing, the serum or plasma specimen reacts with the particle coated with anti-HBsAG antibodies. The mixture migrates upward on the membrane chromatographically by capillary action to react with anti-HBsAG antibodies on the membrane and generate a colored line. The presence of this colored line in the test region indicates a positive result. To serve as a procedural control, a colored line will always appear in the control line region indicating that propet volume of specimen has been added and membrane wicking has occurred.
