What Are Urine Glucose Test Strips?

Urine glucose test strips are special test strips used by urine patients to check their urine condition. According to the catalysis of glucose by glucose oxidase, glucose forms gluconic acid and hydrogen peroxide. Hydrogen peroxide forms water and atomic oxygen under the catalysis of catalase, and atomic oxygen can oxidize a certain colorless compound to colored The principle of the compound is to fix the above two kinds of enzymes and colorless compounds on a paper strip to make an enzyme test paper for testing the urine sugar content.

Urine glucose reflects the average blood glucose concentration during urine collection. Glucose is filtered out in the glomerulus and actively reabsorbed in the proximal tubules. Immerse the reagent end of the test strip in a container containing fresh urine, remove it after about 2 seconds, and compare the changed color of the reagent end of the test strip with the standard color plate on the test strip bottle. Probably judge the content of urine sugar.

Chinese name

Urine sugar test strips

Phenomenon

Light blue, light green, brown, or dark brown in order

Suitable

Urine sugar patients

1. Infiltrate the test strip into the urine (medium urine is the best), and then take it out (about 1-2 seconds) and take it out;

2. Remove the test paper along the edge of the container to remove excess urine;

3. Observe the color of the test strip within 30-60 seconds and compare it with the colorimeter, and measure the result.

4. Judgment of results: (The test strip changes from light blue to brown-red to indicate the test result.) Light blue indicates no diabetes, which is indicated by "-"; brown-red indicates that there is diabetes. The deeper the "+" sign, the more severe the diabetes.

5. According to the amount of sugar in the urine, the test strips show different color changes. Because the color of the test strips varies, the test results obtained are also inconsistent, positive and negative. If the color is blue, it means that there is no sugar in the urine, which represents a negative result. The symbol is (-): green, a plus sign (+), indicating that the urine contains 0.3% -0.5%; it is yellow-green, as Two plus signs (++). It means that 0.5% -1.0% of sugar in urine; orange yellow, three plus signs (+++). Urine contains 1% -2%; brick red, four plus signs (++++) or more, and urine contains more than 2% sugar.

When using test strips, take out all the test strips needed at one time, close the stopper tightly, and store in a cool and dry place.
