Developed for hospital laboratories, addiction treatment centers, and toxicology laboratories, the Thermo Scientific™ DRI™ Fentanyl II Drugs of Abuse Assay is an effective tool for the screening fentanyl abuse and misuse. Its ability to detect both fentanyl and its primary metabolite, norfentanyl gives this assay a broader window of detection compared to competing products. This automated urine drug screening assay exhibits negligible cross-reactivity to other opioids. It is the only 510(k) cleared assay that combines norfentanyl cross-reactivity with a low 1 ng/mL cutoff concentration.
