Description

Test: Urine Reagent Strip‐2L (URS‐2L) Leukocytes/Nitrite Format: Strip Method: Color Indicator Testing Procedure: Manual Storage Temperature: 15‐30°C Expected Values/Sensitivity: Nitrite: No nitrite in normal urine (0.075mg/dL sensitivity) Leukocytes: Normal urine specimens generally yield negative results (10‐15 WBC/µL sensitivity) Limitation of Procedure: Nitrite: The pink color is not quantitative in relation to the number of bacteria present. Any degree of pink coloration should be interpreted as a positive nitrite test suggestive of 105 or more organisms/mL. There are occasional urinary tract infections from organisms which do not contain reductase to convert nitrate into nitrite. Leukocytes: Highly colored urine and the presence of the drugs cephalexin (Keflex®) and gentamicin have been found to interfere with this test. High urinary protein of 500mg/dL or above diminishes the intensity of the reaction color. Elevated glucose concentration or high specific gravity may cause decreased results. Expected Shelf Life: 90 days at 15‐30°C once opened 18 months at 15‐30°C unopened
