Abstract

An analyte testing device is provided for use with a mobile processing device having a camera with a lens, a processor for processing an image captured by the lens. The analyte testing device comprises a casing and a test strip positioner. The test strip positioner positions an analyte containing test strip adjacent to the camera lens to permit the camera to capture an image of the analyte containing test strip. A light source is disposed within the casing. The light source is positioned within the casing to illuminate the analyte containing test strip to facilitate the capture of the image of the test strip. Software is contained within the mobile processing device for performing a quantitative analysis of at least one analyte from the captured image, and providing an output of the results of the quantitative analysis.
