    Urine <t>norfentanyl</t> levels and duration from last fentanyl use Urine norfentanyl levels on day 1 for case 2 (2293 ng/mL) and case 3 (15,234 ng/mL) are presented as axis maximum (>2000) for visibility of low level norfentanyl variability. Values at 2.5 ng/mL, marked by the horizontal line, represent values that were positive on fentanyl immunoassay. However, both fentanyl and norfentanyl were not quantifiable by liquid chromatography-tandem mass spectrometry. Values at 0 ng/mL reflect urine drug tests that were negative by fentanyl immunoassay.
