The Rapid Response^TM Urine Analyzer U121s is a urine test strip reader compatible with the Rapid Response^TM Urinalysis Reagent Strips that stores results and prints reports without the need for special training. It runs a self-test before each urine strip test or each time the power switch is turned on. It is intended for in vitro diagnostic use only. The results will be displayed on the screen and stored in memory after each test.
