Ensure accurate calibration with the DRI Fentanyl II High and Low Control Set, designed for urine screening with the DRI Fentanyl II Drug of Abuse Assay. The control set includes a high and low control, targeted at 1.5 ng/mL and 0.5 ng/mL respectively, to validate the calibration curve by providing positive and negative results.
• Specifically detect fentanyl and its major metabolite, norfentanyl, at physiologically relevant concentrations in human urine
• Low cross-reactivity to other non-fentanyl synthetic opioids and over-the-counter medication
• High sensitivity with a cutoff concentration of 1 ng/mL
