A device and method for performing a rapid immunoassay for a biological analyte containing a positive control analyte which is concurrently tested using the same device and immunochemical reaction as the biological analyte. The positive control analyte is non-crossreactive with the biological analyte to be detected and may be an immunogen or a hapten. The device and method permit operators of the test device, particularly non-laboratory professionals, to determine that an assay is performed correctly and that the device is functioning properly, thereby allowing the operator to have confidence in the accuracy of either a positive or negative result. This is particularly important when a positive result is indicated by the absence of color at a test site, which is counterintuitive with many operators and which frequently occurs with a competitive immunoassay.
