The study evaluated the individual performance of each devices sensitivity, specificity and accuracy at different concentration levels of spiked samples. The other devices assessed alongside Drugwipe® in the independent study were the Dräger® DT5000, ToxSure, iScreen, , Oral Q, Oratect, Oraline, Oral Screen, Saliva Scan and Xalex. According to Center for Forensic Research & Foundation’s findings, the individual performance of these devices on the market were eye opening when compared with independent lab results.
Nine out of 10 devices tested were found to have accuracy and sensitivity levels lower than 100%. Based on the study’s findings, only Drugwipe® by Affiniton® (formerly Securetec® USA) was found to fully meet its advertised sensitivity, specificity and accuracy levels for the drugs outlined and also outperformed every other device by comparison with zero false positives and zero false negatives.
Amidst budget cuts and rolling furloughs, many local police stations can’t afford their already strained payroll let alone pay overtime to their patrol officers in the field. If an on-site saliva screening device lacks accuracy and has a high level of false negatives, it can bring problems to every DUID (Driving Under the Influence of Drugs) traffic stop or inadvertently overlook someone that shouldn’t be driving.
When considering DUID screening tools, the goal for many law enforcement agencies has been to find an on-site drug screening device that is comparable to blood, non-invasive, accurate and quick. With 100% accuracy and zero false negatives, the Affiniton® Drugwipe® 6S saliva screen has user-friendly instructions, a light weight frame, requires a small sample size as a safeguard against dry mouth and fits the bill of a truly portable device.
The initial results of the study were presented at the February 2013 AAFS (American Academy of Forensic Science) conference in Washington, DC. If you would like a pdf presentation of the final study results, please call or email Affiniton® at:
