The test is used for semi-quantitative determination of opiates and their metabolites in urine. Opiates are psychoactive substances such such as morphine, heroin, codeine and others. Opiates affect various areas of the central nervous system, causing abolition of pain, drowsiness, mood changes and impaired consciousness. Heroin - the most popular narcotic of the opiate group, is subject to immediately hydrolyzed in the bloodstream to form 6-monoacetylmorphine, which undergoes further metabolism to morphine or morphine glucuronides are excreted in the urine. About 10% of codeine is converted to morphine, which then undergoes metabolism specific to morphine. As a result, urine from codeine users contains small amounts of morphine, morphine glucuronides and N-normorphine. A positive result semiquantitative, screening test indicates the presence in the urine of him compounds from the drug group in question.
