Abstract
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.
