The test uses chromatography to separate cocaine from other compounds and can not only detect the presence of cocaine but also give quantitative data about the amount of cocaine a person has ingested.<\/div>\n<div>The test was found to offer a level of sensitivity below the cut-off level normally used for oral fluid drug testing, meaning that it can detect even low levels of cocaine in a person\u2019s urine or oral fluid. The technique potentially offers an effective solution for scenarios where a rapid test is required. This could include roadside testing by police of motorists, and also drug testing in the workplace and in prisons.<\/div>\n<div>While there are a number of portable tests for cocaine commercially available, these are mainly based on antibody reagents, which cannot offer quantitative data and \u2013 since the cocaine antibody can bind to something that is not cocaine \u2013 can give false positive results.<\/div>\n<div>The research paper\u2019s lead author, Mahado Ismail of the University of Surrey, explained, \u201cSurface mass spectrometry is used in a wide range of disciplines to obtain chemical information from the surface of a sample. However until now it has not been possible to translate this method to low cost, portable testing.<\/div>\n<div>\u201cThis new method, which extracts analytes from a surface and separates them using chromatography, has been shown to provide a sensitive, accurate result. Our next step will be to test the efficacy of the system for monitoring other drugs of abuse, while we are also looking for follow-on funding to further develop the test.\u201d\n<\/div>\n<div>University of Surrey<\/div>\n<div><link http:\/\/tinyurl.com\/z65q5du _blank external-link-new-window \"Opens internal link in current window\">http:\/\/tinyurl.com\/z65q5du<\/link><\/div>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Chemistry researchers develop a simple diagnostic test that can identify the level of cocaine in a person\u2019s urine or oral fluid.
