Abstract

A method for calibrating a camera of a mobile device for detecting an analyte in a sample. An image of an object is captured using the camera with an illumination source turned on. A first area is determined in the image which is affected by direct reflection of light originating from the illumination source and reflected by the object. A second area which does not substantially overlap with the first area is determined as a target area of a test strip. Also disclosed is a detection in which a sample is applied to a test strip and a visual indication is provided to position the test strip relative to the camera to thereby locate the test field of the strip in the target area. An image of the test field is captured using the camera while the illumination source is turned on, and analyte concentration is determined from the image.
