Urine Test Strip
[Product Name]
Product Name: Urine Test Strip (Dry Chemical Method)
Type: Urine-H-11,Urine-H-10,Urine-H-8,Urine-H-3,Urine-H-1
[Packing Specification]
100 strips / box
[Intended Application]
The urinalysis strip is designed for determination of 11 items, including bilirubin,
urobilinogen, ketone, ascorbic acid, glucose, protein, occult blood, nitrite, leukocyte, pH value
and specific gravity, in human urine. The product can be applied by visual inspection and with
a urine analyzer.
Routine urine test reflects severity and progression of kidney and urinary tract diseases.
Urine of patients with some early urinary system diseases shows proteinuria or visible
components of urinary sediment. Urinalysis shows important referential values for diagnosis
of urinary system disease and observation of the curative effect as well as for diagnosis and
prognosis of other system diseases. For example, it facilitates diagnosis of urinary system
diseases and observation of the curative effect, covering tuberculosis, calculus, vascular or
urinary system inflammation, lymphatic lesion, kidney transplant and others, diagnosis of
metabolic disorders-induced diseases (such as diabetes, pancreatitis, acute hemolytic disease
and others).
[Test Principles]
1. Bilirubin: Direct bilirubin specifically reacts with dichloroaniline diazonium salt under
a strong acid condition to form azo dye.
2. Urobilinogen: According to the principle of azo combination method, urobilinogen
couples with diazonium salt under a strong acid condition to form carmine dye.
3. Urobilinogen: According to the principle of azo combination method, urobilinogen
couples with diazonium salt under a strong acid condition to form carmine dye.
4. Ascorbic Acid: Ascorbic acid reverts blue 2,6-dichlorophenol indophenol sodium in
oxidation state to colorless compound under an alkaline condition.
5. Glucose: According to the principle of glucose oxidase, glucose oxidase specifically
oxidizes glucose to form gluconic acid and hydrogen peroxide. Under the function of
peroxidase, hydrogen peroxide oxidizes the indicator to develop a color.
6. Protein: According to the principle of the protein error method for dye combination,
protein combines with dye to form compound and show another color.
7. Occult Blood: Peroxide is decomposed under the peroxidase-like catalytic effect of
hemoglobin, which oxidizes tetramethyl benzidine to develop a color.
8. Nitrite: Nitrite in urine develops diazo-reaction with sulfanilamide in test paper to
form diazonium salt. The diazo compound later combines with naphthyl-ethylenediamine
dihydrochloride to show a peach color.
9. Leukocyte: Esterase is contained in neutrophil cytoplasm. It hydrolyzes an indoxyl
substrate to release phenol, which reacts with diazonium salt to form purple red compound.
10. pH Value: It is based on acid-alkaline indicator method.
11. Specific Gravity: It is determined with multiple-polyelectrolyte method. Ion
exchange occurs between electrolytes in urine and methyl vinyl acid copolymer.
Positive ions exchange between electrolyte (in the form of salt) in urine and polymer to
release hydrogen ions, which reacts with acid-alkaline indicator, showing a color change.
