The present invention relates generally to an assay for detecting and differentiating multiple analytes, if present, in a single fluid sample, including devices and methods therefore.

Devices for the detection of multiple analytes in a sample

A test device and method for determining the presence or absence of one or more analytes in a fluid sample, the test device including a support or member bearing a mark thereon, and a matrix or member containing a capture zone. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (&#x2212;) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (&#x2212;) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.
