Urinalysis test strip URI10G

proteinbilirubinglucose

URI10G urine reagent strips provide tests for the semi-quantitative measurement of leukocytes, ketone, nitrite, urobilinogen, bilirubin, protein, glucose, specific gravity, blood and pH in urine. For use with the urine analyzer of BT URI500B, BT URI50 . The test is intended for use by health care professionals. SUMMARY URI10G urine reagent strips consist of a plastic strip affixed with reagent papers and a calibration pad. This feature facilitates measurement of multiple urine constituents and use for everyday diagnosis and group examinations. The calibration pad, which is not impregnated with reagents, allows instrumental correction interference from natural color of urine automatically and obtains accurate result. TEST PRINCIPLES AND LIMITATIONS Leukocytes: The test reveals the presence of granulocyte esterases. These esterases cleave an indoxyl ester, and the indoxyl so liberated reacts with a diazonium salt to produce a violet dye. Leukocyte esterase results may be positive in the absence of observable cells if the leukocytes have lysed. Positive results may occasionally be found with random specimens from females due to contamination of the specimen by vaginal discharge. Elevated glucose concentrations (55 mmol/L-110 mmol/L) or high specific gravity may cause decreased test results. The presence of cephalexin, cephalothin, tetracycline may cause decreased reactivity, and high levels of the drug may cause a false negative reaction. The test area does not react with lymphocyte. Reactivity may also vary with temperature Ketone: This test is based on the principle of Legal’s test and is more sensitive to acetoacetic acid than to acetone.
