Abstract
A method is provided for a computing device with an imaging device to detect a characteristic of an analyte in a specimen sample from a specimen test strip with reaction areas that have colors based on the characteristic of the analyte in different ranges of values. The method includes capturing images of the specimen test strip under different exposures or light intensities, selecting an image comprising captured reaction areas that have a proper exposure or a proper lighting intensity from the images, selecting a captured reaction area from the image, and correlating a color of the captured reaction area to a value of the characteristic of the analyte.
