Urine Test Strips

Procedure and Notes • Use only well mixed, non-centrifuged urine, which should not be older than 4 hours. First morning urine is recommended. Protect the samples from light. • If the samples cannot be tested immediately, they should be stored at 2...4°C and brought to room temperature (15...25°C) before testing. • Collect specimen in clean, well rinsed containers, free of detergents. Do not add any preservatives. • Do not touch test areas of the reagent strip. • Immediately after removing the required number of strips, close the container securely using the original cap. • Immerse the test strip in the urine (approx. 2 sec), so that all reagent areas are covered. Remove excess urine from the strip by wiping the edge of the strip on the urine container or on absorbent paper. • To prevent interaction from adjacent test areas, hold the strip in a horizontal position during incubation. • Compare the reagent areas on the strip with the corresponding color chart on the container 60 seconds (60 120 seconds for leucocytes) after immersion. Coloration only on the rim of the test pad or after more than 2 minutes after immersion is without meaning and should not be used for interpretation. • The evaluation should be carried out in diffuse daylight or under a daylight lamp. Light from certain light bulbs can simulate non-specific positive results (protein, leucocytes).
