Abstract: Systems, methods, and test kits for detecting and quantifying an analyte level in a biological fluid sample using impedance measurements, are disclosed. The fluid sample is applied to a lateral flow strip, and impedance of the strip is measured as the assay dries. Analysis of the drying-dependent impedance measurements indicates the presence and quantity of the analyte in the fluid sample.

Abstract: Diagnostic test devices improve communication to a user thereof through provision of audible output. The test device can include a test member, such as lateral flow assay test strip. The test device further includes an electronic communication circuit that can comprise an audio output element as well as a microcontroller. Other elements in the electronic communication circuit includes one or more sensor elements, a display element, and one or more switching elements.—Methods provide indicia for operation of a test device that comprise steps for assembly of a diagnostic test device that provides for audio output.
