About Fentanyl Screen and Confirmation, Urine in Fallbrook
This test is used when a preliminary answer is not sufficient and a definitive identification is needed.
The screening step uses an immunoassay that reacts to fentanyl and, depending on the assay, may cross-react with structurally similar compounds such as norfentanyl or certain fentanyl analogs. A reactive screen is presumptive, not diagnostic, so it is followed by a confirmation step that separates and identifies the drug or its metabolites by mass.
Urine is the specimen because fentanyl and its primary metabolite, norfentanyl, are excreted in urine. Detection windows depend on dose, frequency of use, individual metabolism, and hydration status, so a negative result does not exclude recent exposure and a positive result does not by itself establish impairment.
Results are reported as negative or positive for the screen and, when confirmation is performed, as the specific analyte or analytes identified. The laboratory may also report a cutoff concentration. Interpretation should account for prescribed or administered medications, including fentanyl used in clinical settings, and for any chain-of-custody requirements if the result is intended for a non-clinical purpose.
