Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] A test paper for detecting the range of uric acid content in urine, comprising a test paper substrate 10, characterized in that an enzyme color developer 20 is adhered to the test paper substrate. The enzyme color developing agent 20 is mainly composed of uricase, peroxidase and color developing agent.

[0020] Wherein the composition of the enzyme chromogenic reagent is as follows:

[0021] 4-Aminoantipyrine 4-6mM / L

[0022] 2-Hydroxy-3,5-dichlorobenzenesulfonic acid 18-22mM / L

[0023] Uricase 0.8-1.2ku / L

[0024] Peroxidase 1.88-2.82ku / L

[0025] Ferrous potassium hydride 0.32-0.48mM / L

[0026] Phosphate buffer 1.2-1.8M / L

[0027] Dip the test paper base strip 10 into the enzyme color reagent 20, take it out, and dry it at low temperature.

[0028] The reagent attached to the test strip can generate a red quinimine substance with uric ac...

Abstract

The invention relates to a test paper strip of using color reaction to detect the concentration of uric acid in urine. It includes test paper base material, its feature is that: enzyme color developing reagent adheres to test paper base material. The beneficial effect of this invention is that, the detector can detect the concentration of uric acid in urine in own home, so as to preliminary reach the range of uric acid content in the urine, thus it is certain guiding significance for the blood uric acid content.

Description

Technical field [0001] The invention relates to a test paper strip for detecting the concentration of uric acid in urine by using color reaction, which is used for quantitatively and rapidly measuring the level of uric acid in urine. Background technique [0002] Uric acid is the oxidative decomposition product of purine base, which has no physiological function in the human body. The main sources of purine in the human body are diet, tissue decomposition and de novo synthesis. Uric acid is the end product of purine metabolism in humans. Under normal circumstances, it is mainly excreted by the kidneys, accounting for about 2 / 3, and the rest is excreted through the intestines, skin, and hair. Currently, blood uric acid is mainly tested on large blood biochemical analyzers. However, the problems of this method are that special devices are required, the measurement requires a large amount of blood, takes a long time, and is expensive, which is generally only possible in larg...
