HEPACARD is a one step immunoassay based on the antigen capture, or "sandwich" principle. The method uses monoclonal antibodies conjugated to colloidal gold and polyclonal antibodies immobilized on a nitrocellulose strip in a thin line.The test sample is introduced to and flows laterally through an absorbent pad where it mixes with the signal reagent.If the sample contains HBsAg, the collodial gold-antibody conjugate binds to the antigen, forming an antigen-antibody-collodial gold complex. The complex then migrates through the nitrocellulose strip by capillary action. When the complex meets the line of immobilized antibody(Test line) "T", the complex is trapped forming an antibody-antigen-antibody colldial gold complex. This forms a pink band indicating the sample is reactive for HBsAg. To serve as a procedural control, an additional line of anti-mouse antibody (Control line) "C", has been immobilized at a distance from the test line on the strip.If the test is performed correctly, this will result in the formation of a pink band upon contact with the conjugate.
