Urinalysis test strip URI12F

nitritepHmicroalbumin

URI12F urine reagent strips provide tests for the semi-quantitative measurement of nitrite ,leukocytes,ketone,creatinine,urobilinogen,bilirubin,protein,glucose,specific gravity, blood , pH and microalbumin in urine. Use with the BT URICELL 1600, URIT 1500,1600,1610 automatic urine analyzer and URIT330 , 560 urine analyzer SUMMARY URI12F 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 Nitrite: The test is based on the principle of Griess’s test and is specific to nitrite. Any degree of uniform pink colour development should be interpreted as a positive. Nitrite test suggesting the presence of 105 or more organisms per mL, but colour development is not proportional to the number of bacteria present. A negative result does not in itself prove that there is no significant bacteriuria. Negative results may occur when urinary tract infections are cause by organisms which do not contain reductase to convert nitrate to nitrite; when urine has not been retained in the bladder long enough (4-8hrs) for reduction of nitrate to occur; or when dietary nitrate is absent, even if organisms containing reductase are present and bladder incubation is ample.
