About Fentanyl Screen and Confirmation, Urine in Fallbrook
This test is used when a precise answer about recent fentanyl exposure is needed, rather than a single rapid screen alone.
The screening phase uses an immunoassay to flag specimens that may contain fentanyl or its metabolites. Because immunoassays can cross-react with other substances, a reactive screen is not considered definitive on its own.
The confirmation phase uses a more specific technique, such as gas or liquid chromatography coupled with mass spectrometry, to identify fentanyl and its major metabolite, norfentanyl, by their chemical properties. This step distinguishes true positives from substances that may have caused a false screen reaction.
Results are typically reported as negative or positive, with the confirmation step providing the definitive finding. Detection windows depend on dose, frequency of use, metabolism, and hydration; fentanyl and norfentanyl are generally detectable in urine for a relatively short period after last exposure.
