About Fentanyl Screen and Confirmation, Urine in St. Charles
Fentanyl is a potent synthetic opioid that can be detected in urine after use or exposure.
The test involves an initial immunoassay screen that provides a preliminary result. If the screen is non-negative, a confirmation method such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) is performed to definitively identify fentanyl or its primary metabolite, norfentanyl.
Urine is the preferred specimen for detecting recent fentanyl exposure, as metabolites are typically excreted within hours and can remain detectable for one to three days, depending on factors like dosage, frequency of use, and individual metabolism.
Results are reported as negative or positive. A negative screen indicates that fentanyl was not detected at the assay's cutoff concentration. A positive confirmation provides definitive evidence of fentanyl or norfentanyl in the sample. The test does not measure impairment or quantify the amount of drug present.
