Urinalysis test strips refer to test strips that test for bilirubin, urobilinogen, ketone bodies, ascorbic acid, glucose, protein (albumin), blood cells, PH, etc. in urine.
Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
