METHOD FOR RE-USING TEST PROBE AND REAGENTS IN AN IMMUNOASSAY

摘要

The present invention is directed an immunoassay method, which re-uses an antibody-immobilized test probe and reagents for quantitating an analyte in different samples, anywhere from about 3 to 20 times, while maintaining acceptable clinical assay performance. The method regenerates the test probe after completion of each cycle of reaction. The present invention is also directed to a unitized cartridge (a strip) for an immunoassay test. Each unitized cartridge contains all necessary reagents can be used for 3-20 cycles to measure 3-20 different samples.
