1. A method for color-based reaction testing of biological materials comprising the acts of: capturing digital image information of an exposed test strip and a reference color chart in an 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 arranged in a plurality of test-specific sequences; locating first image data within the digital image information corresponding to each of the plurality of test pads, said first image data having color information; locating second image data within the digital image information corresponding to each of the plurality of color blocks on the reference color chart, said second image data having color information; matching color information from the first image data to corresponding color information from the second image data; and generating test results based on said matching.
