ABSTRACT:
A chromatographic assay device for detection and/or determination of an analyte in a competitive immunoassay gives a semiquantitative or quantitative indication of analyte concentration in a single assay device while also giving a positive indication that flow has occurred properly through the device. In one form, the device comprises: (1) a first opposable component including a sample preparation zone and an absorber; and (2) a second opposable component including a first chromatographic medium with capture and detection zones, a second chromatographic medium with a comparison zone, and a comparison label. In another form, the second opposable component includes one chromatographic medium with capture, detection, and control zones. Test kits incorporating the devices and methods for their use are also disclosed.
