Urinalysis test strip URS-3

for glycosuriafor proteinuriapH

Teco Diagnostics is proud to introduce our complete line of Urinalysis products. From our world renowned Urine Reagent Strips (URS) to our semi-automated Urine Strip Readers. 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) 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) 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. pH: If proper procedure is not followed and excess urine remains on the strip, a phenomenon known as “running over” may occur, in which the acid buffer from the protein reagent are runs onto the pH area, causing a false lowering in the pH result. Protein: False positive results may be obtained with highly alkaline urine. Contamination of the urine specimen with quarternary ammonium compounds may also produce false positive results. Expected Shelf Life: 90 days at 15‐30°C once opened 18 months at 15‐30°C unopened
