Abstract
A method for a mobile computing device with a camera and a screen to measure a test strip in a test strip module includes, in a calibration phase before a sample is introduced to a reaction area on the test strip, detecting with the camera an ambient light effect when the test strip module is mounted on the face of the mobile computing device. In a measurement phase after the sample is introduced to the reaction area on the test strip, the method also includes illuminating the test strip with a light provided by a light source area on the screen, detecting with the camera one or more colors of the reaction area, correcting the detected one or more colors for the ambient light effect, correlating the corrected one or more colors to an analyte property, and displaying a value of the analyte property on the screen.
