RAPID IMMUNOASSAY FOR DETECTION OF ANTIBODIES OR ANTIGENS INCORPORATING SIMULTANEOUS SAMPLE EXTRACTION AND IMMUNOGENIC REACTION

摘要

The present invention is drawn to an immunoassay capable of the rapid detection of a variety of test substances that may be present in a test sample. One feature of the invention is that extraction or isolation of the test substance occurs simultaneously with the formation of the primary antigen-test substance complex. The primary antigen-test substance complex is then captured in a solid phase format having a plurality of interstitial spaces which facilitate rapid and efficient detection. The immunoassay of the present invention works over a wide range of environmental conditions and is simple enough to be used in the absence of laboratory facilities.
