In order to demonstrate an intake of cannabis, there are a number of rapid tests, all of them being focused on urine. In this study, we evaluated the results of six tests when applied to sweat (DrugWipe), saliva and urine (Syva Rapidtest, Biomedix, Frontline, DrugWipe, Cortez Dako). Fifty regular users of cannabis and fifty persons who denied consuming it were studied. The results obtained with DrugWipe in sweat were compared with anamnesis data, whereas results obtained in saliva and urine were compared with those of gas chromatography--mass spectrometry. The results indicate that DrugWipe may be useful for screening cannabis in sweat when the intake took place less than two hours before. The results obtained in saliva showed that none of the tests studied are reliable to be used with this medium, because of the great number of false positive and false negative results. With urine, four tests (Syva Rapidtest, Biomedix, Cortez, Dako) led to very good results and may be recommended when an immediate presumptive test result is required.
为了证明大麻的摄入量,有许多快速检测方法,所有这些方法都集中在尿液检测上。在本研究中,我们评估了六种检测方法应用于汗液(DrugWipe)、唾液和尿液(Syva Rapidtest、Biomedix、Frontline、DrugWipe、Cortez Dako)时的结果。研究了五十名大麻经常使用者和五十名否认使用过大麻的人。将DrugWipe在汗液中获得的结果与问诊数据进行比较,而在唾液和尿液中获得的结果与气相色谱-质谱分析结果进行比较。结果表明,当摄入时间在两小时以内时,DrugWipe可能有助于筛查汗液中的大麻。唾液检测结果表明,由于大量的假阳性和假阴性结果,所研究的检测方法均不可靠用于该介质。对于尿液,四种检测方法(Syva Rapidtest、Biomedix、Cortez、Dako)得出了非常好的结果,当需要即时推定检测结果时可以推荐使用。
