Abstract
The present invention provides an assay device for determining the presence of one or more selected analytes in a sample. The device includes a housing having an exterior surface and defining an interior area. A sample receptor receives the sample. A sample treatment strip reacts the sample with a reagent to yield a physically detectable change which correlates with the amount of selected analyte in the sample. A detector responds to the physically detectable change and produces an electrical signal which correlates to the amount of the selected analyte in the sample. A processor converts the electrical signal to a digital output. A starter automatically activates the processor and detector upon the application of the sample to the device. A display visually displays the digital output external to the housing and is connected to the processor. The present invention also provides a method for determining the presence of one or more selected analytes in a sample within a disposable housing, automatically starting a diagnostic device to analyze a sample, and displaying quantitative assay results for a plurality of selected analytes in a sample on a diagnostic device.
