Abstract

A method for detecting an analyte in a sample is disclosed. The method includes providing a mobile device having a camera and an illumination source. A test strip having a test field with at least one test chemical for performing an optical detection reaction in the presence of the analyte is provided. The sample is applied to the test field. Several images of a region of the test strip are captured. The region includes at least part of the test field to which sample is applied. The images are captured before and after the sample is applied and with the illumination source turned on and off. The images captured are compared and differences in light intensities are determined. Analyte concentration is determined using the images captured and the determined light intensities.
