"The three tested on-site screening devices, Mavand RapidSTAT®, Securetec Drugwipe-5+® and Dräger DrugTest 5000® were able to detect about 70% of all cocaine and cannabis users in a roadside setting. Amphetamine/MDMA users were detected more easily with a sensitivity higher than 92%. The sensitivity of the oral fluid screening tests for THC is increasing as manufactures are still trying to lower the cut-off of their devices. First results using the new DrugTest 5000 test cassette® demonstrate that a sensitivity of 93% is possible."
