Ensure accurate calibration with the DRI Fentanyl II Drugs of Abuse Calibrators, designed for urine screening with the DRI Fentanyl II Drug of Abuse Assay. The calibrators, sold separately, include a negative urine calibrator and a cutoff calibrator spiked with 1 ng/mL of fentanyl.
• 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
