CA 2330901

One embodiment of the present invention improves the vis- ual use of urine test strips and reagent pads by providing a single color from a reference color spectrum directly on the colorimetric strip and adjacent to the reagent area to allow easy comparison. After application of a fluid to be tested to a reagent area on the colorimetric strip, a technician is able to easily compare the color in the reagent area to the refer- ence color area(s) to determine the presence or absence of, for example, glucose, in the fluid placing at least one ref- erence color immediately next to the reagent area markedly im- proves technician's accuracy in comparing and analyzing the reagent area against the reference color(s). The present in- vention allows a technician to easily and quickly compare a reagent area color to more than one reference area to deter- mine the actual numerical value of, for example, the pH in the tested fluid.
