Abstract: A method is provided for a computing device with an imaging device to read a specimen test strip. The method includes capturing an image of the specimen test strip, wherein the image includes a reaction area, a color calibration area, and a temperature calibration area on the specimen test strip, determining a color of the reaction area based on one or more colors of the color calibration area, and determining a value of a characteristic of an analyte by correlating the color of the reaction area to the value and then adjusting the value based on the color of the temperature calibration area, or adjusting the color of the reaction area based on the color of the temperature calibration area and then correlating the color of the reaction area to the value.

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.

Abstract: A specimen test strip is provided to detect a characteristic of an analyte in a specimen sample. The specimen test strip includes a reaction area to receive the specimen sample and a color calibration area to determine a color, or a color and a color intensity, of the reaction area after receiving the specimen sample. The specimen test strip may further include a temperature indication area to correct a measurement of the characteristic of analyte.
