1. A method to determine exposure of a diagnostic instrument to a hostile environment, the method comprising:
capturing a first digital image of at least a portion of a diagnostic instrument, the portion of the diagnostic instrument comprising at least one color reference including a plurality of reference samples of different colors, at least one test medium having a reagent that changes color in a presence of particular analytes in a biological sample, and at least one contamination detection medium having a reagent that changes color in the presence of being exposed to a hostile environment;
identifying at least one reference sample of the plurality of reference samples in the diagnostic instrument;
determining a dominant camera-captured color of the at least one reference sample and a dominant camera-captured color of the at least one contamination detection medium;
color correcting the dominant camera-captured color of the at least one contamination detection medium to determine a first corrected contamination detection medium color in response to a correction factor derived at least in part from the dominant camera-captured color of the at least one reference sample; and
comparing the first corrected contamination detection medium color to a predetermined exposure detection color range to determine an exposure detecting result.
