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.
