Fentanyl Urine Test – Box of 50
Our fentanyl urine test (box of 50) detects norfentanyl (the primary fentanyl metabolite) at a cut-off of 20 ng/mL with a documented accuracy of 99.2%. Detection window is 1–3 days.
Fentanyl is a synthetic opioid estimated to be 50–100x more potent than morphine. Fentanyl-contaminated street drugs are increasingly common across Europe, making this test important for both harm reduction and workplace screening programmes.
