OPTIMIZING SENSITIVITY IN COLLOIDAL COLORIMETRIC FLOW THROUGH AND LATERAL FLOW TESTS

摘要

An immunoassay test device is disclosed that allows for easy identification of positive reactions. The test device provides a simplified, sensitive and specific test procedure for the determination and detection of an immunologically reactive analyte in an aqueous sample. The test device comprises a plastic enclosure (2) having a top section (3) and a bottom section (4). The top section (3) of enclosure (2) has an opening (7) for receiving sample and an opening (8) for visualizing test results (9) and for visualizing a control result (10). Bottom section (4) comprises a tray (11) into which fits a capture membrane (12). The capture membrane (12) aligns a capture antibody on a solid surface so that the capture capability of the capture antibody is not sterically hindered.
