    Abstract: An analytic test device of a one time use type formed by concentrically disposed tube and sleeve members. A test reagent is present in the annular region between tube and sleeve. A liquid sample placed inside the tube is unable to enter the reagent containing annular region until relative movement between tube and sleeve opens a passage for sample flow into the annular region and contact with the test reagent.The test device is particularly adapted to testing urine samples.
