The Webster's test is a qualitative urine test used to detect the presence of trinitrotoluene and its metabolites.[1] The test was developed in 1917 by T.A. Webster[2] in London as a way to test for trinitrotoluene poisoning. A positive test results in a purple color for the acidified urine samples.
