Product category: Urinalysis equipment and systems
Test: Urine Reagent Strip‐9 (URS‐9) Nitrite/Urobilinogen/Protein/pH/Blood/SG/Ketone/Bilirubin/Glucose Format: Strip Method: Color Indicator Testing Procedure: Manual Storage Temperature: 15‐30°C Expected Values/Sensitivity: Glucose: Concentrations as little 0.1g/dL may be significantly abnormal if found consistently (100mg/dL sensitivity) Bilirubin: No bilirubin in normal urine (0.4‐0.8mg/dL sensitivity) Ketone: No ketones in normal urine (5‐10mg/dL sensitivity) Specific Gravity: Random urine varies in specific gravity from 1.003‐1.040+ (correlates within 0.005 with values obtained with the refractive index method) Blood: No blood in normal urine (0.015mg/dL sensitivity) pH: Newborn: 5.0‐7.0; Thereafter: 4.5‐8.0 ; Average: 6.0 (quantitative differentiation of values to one unit) Protein: 1‐14mg/dL may be excreted by the normal kidney (15mg/dL sensitivity) Urobilinogen: 0.2‐1.0 EU/dL in healthy urine (0.2 EU/dL sensitivity) Nitrite: No nitrite in normal urine (0.075mg/dL sensitivity) Limitations of Procedure: Glucose: Moderate amounts of ketone bodies (40mg/dL or greater) may decrease color development in urine containing small amounts of glucose (75‐125mg/dL). However, such concentration of ketone simultaneously with such glucose concentration is metabolically improbable in screening. The reactivity of the glucose test decreases as the specific gravity and/or ascorbic acid of the urine increases. Reactivity may also vary with temperature. Bilirubin: Reactions may occur with urine containing large doses of chlorpromazine or rafampen that might be mistaken for positive bilirubin. Indican (indoxyl sulfate) and metabolites of Lodine® may cause false positive or atypical color; ascorbic acid (25mg/dL or greater) may cause false negative results. Ketone: Color reaction that could be interpreted as “positive” may be obtained with urine specimens containing MESNA or large amounts of phenylketones or L‐dopa metabolites. Specific Gravity: The chemical nature of the specific gravity test may cause slightly different results from those obtained with the specific gravity methods when elevated amounts of certain urine constituents are present. Highly buffered alkaline urine may cause low readings relative to other methods. Elevated specific gravity readings may be obtained in the presence of moderate quantities (100‐750mg/dL) of protein.
