Abstract:
1. A method for color-based reaction testing of biological materials comprising the acts of: capturing, by an electronic device using ambient lighting in an uncalibrated environment, digital image information of an exposed test strip and of a reference color chart, wherein the digital image information of each of the exposed test strip and the reference color chart is captured in the same uncalibrated environment, wherein the exposed test strip comprises a plurality of test pads, and wherein further the reference color chart comprises a plurality of color blocks; locating, by a diagnostic software application that is executing on the electronic device, first image data within the digital image information corresponding to each of the plurality of test pads, said first image data having uncalibrated color information; locating, by the diagnostic software application executing on the electronic device, second image data within the digital image corresponding to the plurality of color blocks on the reference color chart, said second image data having uncalibrated color information; matching, by the diagnostic software application executing on the electronic device, uncalibrated color information from the first image data to corresponding uncalibrated color information from the second image data, wherein said matching comprises comparing uncalibrated color information corresponding to a first test pad of the plurality of test pads to uncalibrated color information from at least one of the plurality of color blocks on the reference color chart; generating, by the diagnostic software application executing on the electronic device, test results based on said matching; and displaying, on a display screen of the electronic device, a graphical representation of the test results indicating an absence, presence and degree of presence of a reactant within the biological specimen.
