A test device, test composition, and method are disclosed for determining the presence of a component in a sample. The device comprises a carrier matrix incorporated with a reactant system which produces a detectable response upon contact with the sample component. After a predetermined time interval elapses, the production of the detectable response is terminated by an inhibitor system also incorporated with the matrix. The test composition comprises the reactant and inhibitor systems. The method of use comprises contacting the test device with a test sample suspected of containing the component, permitting a predetermined time to elapse after contacting, and observing any detectable response produced.

A method for detecting the presence of a component in a sample, the method comprising; a. contacting said sample with a carrier matrix incorporated with (i) a reactant system which, upon contact with said sample, interacts with said component to produce a detectable response, and (ii) an inhibitor system which, upon contact with said sample, prevents the reactant system from interacting with the component after a predetermined time, b. incubating the matrix, after contact with the said sample, for said predetermined time, and c. observing said detectable response.
