Summary
This study, conducted by the National Highway Traffic Safety Administration (NHTSA), evaluates the performance of five portable oral fluid drug screening devices intended for field use in impaired driving cases. The research was motivated by the growing popularity of oral fluid as a non-invasive alternative to blood and urine for drug detection, which offers advantages such as easier collection, reduced adulteration risk, and better correlation with observed impairment symptoms. However, no standardized program previously existed to assess the suitability of these point-of-contact devices for law enforcement applications. The study aimed to determine the accuracy, reliability, susceptibility to interference, and environmental resistance of these devices against manufacturer specifications and established performance benchmarks. The researchers selected five commercially available devices: Dräger DrugTest 5000 (DDT5000), Dräger DrugCheck 3000 (DDC3000), Securetec DrugWipe S 5-Panel (DrugWipe), Alere DDS2 Mobile System (DDS2), and AquilaScan. Testing was conducted in a laboratory setting using oral fluid samples prepared with target analytes at specified concentrations. The evaluation criteria were based on recommendations from two prior major studies: the Roadside Testing Assessment (ROSITA), which required greater than 90% sensitivity and specificity and greater than 95% accuracy, and the Driving Under the Influence of Drugs, Alcohol and Medicines (DRUID) project, which required greater than 80% sensitivity, specificity, and accuracy. The devices were tested for their ability to detect cannabinoids, opiates, cocaine, methamphetamine, amphetamine, and, in some cases, methadone or benzodiazepines. The results revealed significant variability in performance across the devices. The DDT5000 and DDC3000 demonstrated aggregate performance consistent with ROSITA requirements, achieving high sensitivity (99.1% and 97.2%, respectively) and specificity (99.2% and 100.0%). The DDS2 device met ROSITA requirements in aggregate, though its specific THC assay did not. In contrast, neither the DrugWipe nor the AquilaScan met ROSITA performance requirements individually or in aggregate; AquilaScan showed particularly low sensitivity at 21.7%. All three devices that met ROSITA standards (DDT5000, DDC3000, and DDS2) also satisfied the lower DRUID performance thresholds. Regarding interference, chewing tobacco caused frequent false positives and negatives across all devices, while coffee, milk, soda, and wintergreen produced inconsistent results. However, incorporating a 10-minute waiting period prior to testing eliminated the effects of these potential interferents. The study concludes that while oral fluid screening devices offer practical advantages for field use, their reliability varies significantly by model and drug class. The DDT5000, DDC3000, and DDS2 are viable options that meet established scientific standards for sensitivity and accuracy, whereas the DrugWipe and AquilaScan do not. Importantly, the authors emphasize that all tested devices are screening tools only; positive results in field use must be followed by confirmatory laboratory testing. The findings provide critical data for law enforcement agencies and policymakers selecting appropriate technologies for roadside drug detection programs.
Key finding
The Dräger DrugTest 5000 and Dräger DrugCheck 3000 met the high-performance standards recommended for roadside drug screening, whereas the DrugWipe and AquilaScan devices did not meet these benchmarks.
