URS-1K strips for Urinalysis are firm plastic strips to which a ketone reagent area is affixed. URS-1K strips are packaged along with a drying agent in a plastic bottle with a twist off cap. Each strip is ready to use upon removal from the bottle. The entire reagent strip is disposable. Results are obtained by direct comparison of the test strip with the color blocks printed on the bottle label.

Always store in a cool, dry place and remove only enough strips for immediate use. Do not touch the test area of the strip and replace the cap immediately and tightly. Dip reagent end of strip in FRESH, well mixed, uncentrifuged urine and immediately remove. An alternative method is to pass the reagent strip quickly through the urine stream. While removing, run the edge of the strip against the rim of the urine container to remove excess urine. Compare the test area with the corresponding color chart at the time specified. Each specific parameter will offer a reading time and a color chart for comparison. Again, you must wait the specified time before an accurate level is detected. Reading times are usually in the one minute range. It is possible, due to unusual circumstances, that reading times may take a few seconds longer than noted. If this should occur, just wait until the color has completely changed, then read the color comparison chart. A urine reagent strip will not read a specific level for a particular parameter with the color chart, but rather a range, as noted above for ketones, ranging from a negative to trace to small, moderate or large. It simply reads whether or not a parameter is present and if so, a range of the amount present in the urine.
