About Fentanyl Screen and Confirmation, Urine in Berkeley
This panel combines an initial immunoassay screen with a confirmatory technique such as gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry.
The screening portion of the panel uses an immunoassay that reacts to fentanyl and, depending on the assay, certain related compounds. A reactive screen is considered presumptive and is not, by itself, a definitive identification.
When the screen is reactive, the confirmation step analyzes the same specimen with a more selective method. That method separates and identifies specific molecules, allowing the laboratory to report whether fentanyl or a designated metabolite is present and, in many cases, at what concentration.
Urine is the specimen because fentanyl and its metabolites are excreted in urine over a detectable window after use. Detection times vary with dose, frequency, metabolism, and hydration, so a negative result does not necessarily rule out earlier exposure. Results are reported as negative or positive, with confirmation findings and any measured levels included when applicable.
