Abstract

Clinical test strips were developed by the Bayer Corporation in the 1960s for rapid and simple analysis of urine samples. The test strips consist of a waterproof plastic strip with reagent-impregnated pads that undergo color changes to indicate pH or the presence of protein, glucose, or blood. The blood diagnostic is based on the fact that the heme iron complex catalyzes the reaction between diisopropylbenzene dihydroperoxide with 3,3′,5,5′-tetramethylbenzidine to give a green or blue color. Bayer (2003) specifies that optimal results require the use of fresh, well-mixed, uncentrifuged urine.
