The present invention relates to an improved immunoassay device for confirming the validity of a test result showing either the presence or absence of an analyte in a patient sample. In the improved device, control reagents are provided in the device which directly mimic the reaction of the sample analyte with the test reagents of the device. The device thus allows the user to verify the efficacy of the test reagents at all stages of interaction with the sample analyte.

Assay devices with mobile control reagents

A method of performing a rapid assay for the simultaneous detection and differentiation of the analytes HIV-1 group M. HIV-1 group O and HIV-2 utilizing a sequence specific polypeptide of each analyte as capture reagents. An analytical. device also is provided for performing the method which includes these capture reagents. Also provided is a test kit which includes the analytical device which further can include a positive and negative control.
