Urinalysis strips
In urine reagent strips (URS), enzyme reactions are adopted to quantitatively detect different chemical compounds in human urine specimen.

Urinalysis Strips
Urinalysis strips, also called Urine Reagent Strips (URS), are dip-and-read style of chemical reagent strips, which are used to quasi-quantitatively evaluate the concentrations of the chemical components in human urine specimen, such as urine glucose, bilirubin etc. up to 14 parameters, which are indicators of the health conditions of human body.
The testing results of medical urine reagent strips can provide health information regarding the status of carbohydrate metabolism, kidney function, and acid-base balance etc.
Enzyme Reaction Principle
The rapid dip and read urinalysis strips are based on the enzyme reaction. Each test strip consists of a plastic strip attached with different reaction pads. The reaction pads employs a solid-phase chemistry system, which uses highly specific enzyme reactions to develop different colors corresponding to the concentrations of the target compounds in human urine. By comparing the developed colors with the standard color chart, the concentrations can be quantitatively determined.
