Abstract

The KDI Quik test is a rapid qualitative method for detecting narcotics, cocaine, PCP, and amphetamines in urine. The accuracy of this test was evaluated by testing 106 clinical toxicology urine specimens. Three investigators independently reviewed the test results and compared them to results of standard toxicological analyses. Of 83 samples found positive by the reference technique, only 70 were correctly identified as positive on the Quik test only nine of 23 truly negative controls were correctly identified as negative by the Quik test. The overall sensitivity of the test was 84.7% while the specificity was 39.1% As inaccuracies of this degree could result in frequent clinical error, use of the Quik test is not recommended.
