Norfentanyl Level 1 Control (3.75 ng/mL)

The LZI Fentanyl (Semi-Quantitative) Enzyme Immunoassay is intended for the semi-quantitative determination of norfentanyl in human urine at the cutoff value of 5 ng/mL when calibrated against norfentanyl. The assay is designed for use with a number of automated clinical chemistry analyzers. This is a non-FDA approved assay for Forensic Use Only and as such should not be repackaged for in vitro diagnostic use.
