About 14% of all substance abuse urine tests are positive for 1.2 substances. Cannabinoid and cocaine metabolites are most frequently the cause of positivity. Individuals in probation or parole programs have the highest numbers of positive urine substance abuse tests. Our data suggest that a consistency of positivity exists for substance abuse urine tests and that this positivity, once developed by testing laboratories, can be used for purposes of contractual relations and cost predictions. Valuable educational information that may assist the population serviced by the laboratory in regard to substance abuse can also be obtained.
在所有药物滥用尿液检测中，约14%的检测结果显示1 - 2种物质呈阳性。大麻素和可卡因代谢物是导致检测呈阳性的最常见原因。处于缓刑或假释项目中的人员尿液药物滥用检测呈阳性的比例最高。我们的数据表明，药物滥用尿液检测存在阳性结果的一致性，而且一旦检测实验室得出这种阳性结果，就可用于合同关系和成本预测。还能获取有价值的教育信息，以帮助实验室服务人群了解药物滥用问题。
