Abstract
Systems and methods for a color board for use in reagent strip testing are disclosed. One implementation may include a color board surface, a first colored reference element printed on the color board surface, and a second colored reference element printed on the color board surface. The color board may also include a test region on the color board surface configured to receive at least one reagent pad. The color board may also include a unique code, and the code may reflect specific chromatic properties associated with each of the first colored reference element and the second color reference element at a time of printing. The unique code may be machine readable to enable a machine to later normalize a comparison color, for determining chromatic properties of the at least one reagent pad.
