Abstract
The present disclosure relates to using color calibration to improve and increase the accuracy of interpreting color-sensitive results from test strips made of substrates like paper. This is accomplished via a diagnostic test unit including a substrate, at least one region on the substrate, a reagent placed within the region to react, and a series of color legends on the substrate. Different reagent samples may be placed on the separate regions of a substrate for testing. An imaging device is used to capture the reaction results. More precise readings can be obtained by comparing the reaction results to the color legends to determine the measured property of the analyte.
