The urine test strip test for blood is based on hemoglobin's pseudo peroxidase activity in catalysing a reaction between hydrogen peroxide and the chromogen tetramethylbenzidine in order to produce a dark blue oxidation product. [6] [13] the resultant colour can vary between green and dark blue depending on the amount of hemoglobin. [13]
The first-generation devices relied on the same colorimetric reaction that is still used nowadays in glucose test strips for urine. Besides glucose oxidase, the test kit contains a benzidine derivative, which is oxidized to a blue polymer by the hydrogen peroxide formed in the oxidation reaction. The disadvantage of this method was that the ...

Test strips for glucose contain the enzyme glucose oxidase, which breaks down glucose and forms hydrogen peroxide as a byproduct. In the presence of a peroxidase enzyme, hydrogen peroxide reacts with a chromogen to induce a color change. [51] The presence of glucose in the urine is known as glycosuria.
