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.
Dip test patch of a fresh strip into urine sample or pass through urine stream, 1-2 seconds only. Blot excess on a clean paper towel or tissue. Results should be compared at 40 seconds after exposure to urine. Low-carb dieters use these strips to monitor ketone output in urine which can be an indicator of diet success. Contact your doctor if you have any questions about the results.
