MH medical product Analysis urine strip ph paper strips

Urine Analysis Test Strip   Intended Use Urinalysis test strips are in vitro diagnostic test devices for qualitative and semi-quantitative urinalysis. The strips are for professional use only.   Urinalysis test strips are intended for use to detect conditions indicating possible diabetes, metabolic abnormalities, liver diseases, kidney function, and urinary tract infections. Test results can be used along with other diagnostic information to rule out certain disease states and to determine if microscopic analysis is needed.     Color chart: Test Priniciples

Urobilinogen	This test is based on the Ehrlich reaction in which p-diethylamino benzaldehyde in conjunction with a color enhancer reacts with urobilinogen in a strongly acid medium to produce a pink-red color.
Bilirubin	The direct bilirubin and dichlorobenzene diazonium produce fuchsia azo dyes in a strongly acid medium.
Ketone	The acetoacetate and sodium nitroprusside cause a reaction in the alkaline medium, which produces a violet color.
Blood	Hemoglobin acts as a peroxidase. It can cause peroxidase to release neo-ecotypes oxide [O]. [O] oxidizes the indicator and causes the color change.
Protein	The test is based on the protein-error-of-indicators principle. An ion in the specific pH indicator attracted by cation on the protein molecule makes the indicator further ionized, which changes its color.
Nitrite	Nitrite in the urine and aromatic amino sulphanilamide are diazotized to form a diazonium compound. The diazonium compound reacting with tetrahydro benzo(h) quinolin 3-phenol causes the color change.
Leukocytes	Granulocyte leukocytes in urine contain esterase that catalyze the hydrolysis of the pyrrole amino acid ester to liberate 3-hydroxy-5-pheny pyrrole. This pyrrole reacting with diazonium forms a purple color.
Glucose	The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen. Peroxide hydrogen releases neo-ecotypes oxide [O] under the function of peroxidase. [O] oxidizes iodide potassium, which causes the color change.
Specific Gravity	Electrolyte (M+X-) in the form of salt in urine reacts with poly methyl vinyl ether and maleic acid (-COOH), which is a weak acid ionic exchanger. The reaction produces hydrogenous ionogen, which reacts with a pH indicator that causes the color change.
pH	Applied to acid alkali indicator method.
