Discussion
Another clinical diagnostic technique for measuring levels of glucose in urine is Clinistrip. One end of the plastic strip contains glucose oxidase and an organic dye. Glucose oxidase oxidizes glucose to gluconic acid with the formation of hydrogen peroxide. The hydrogen peroxide reacts with o-toluidine to produce a blue color. The color of the strip is related to the amount of glucose present. This test is very specific for glucose since the glucose oxidase enzyme does not react with many other compounds (including some drugs) that are readily oxidized and give positive Benedict's tests.
