Abstract
An image of a test receptacle is received, which includes a color of a reaction between a test substance and at least one reagent in the test receptacle, an alignment code having test receptacle identification information, and at least one color calibration block. An array of pixels of RGB values for each pixel in the image is collected. A captured color of the color calibration block is evaluated. An offset is determined for the captured color in the one color calibration block if the evaluation of at the color calibration block in the image determines that the captured color deviates from a baseline color. The offset is applied to each pixel in the image to correct the captured image. A colorimetric analysis is performed on the reaction between the test substance and the at least one reagent.
