Order Fentanyl Screen and Confirmation, UrineThe Fentanyl Screen and Confirmation, Urine Profile is a laboratory panel designed to detect and verify the presence of fentanyl and certain related compounds in a urine specimen.

About Fentanyl Screen and Confirmation, Urine in Keystone
Fentanyl is a synthetic opioid that can appear in urine as the parent drug and as metabolites, depending on how and when it was used.
The screen portion uses an immunoassay that reacts to fentanyl and, depending on the assay, may cross-react with structurally similar compounds. Because screening methods are intended to be sensitive rather than definitive, a reactive result is typically described as presumptive.
The confirmation portion uses a chromatographic technique, most often liquid chromatography with tandem mass spectrometry, to identify fentanyl and selected metabolites by their chemical properties. This step reduces the chance that a structurally related substance is mistaken for fentanyl.
Results are generally reported as negative or positive for the screen and separately for the confirmation, with the confirmation listing the specific analytes detected. Detection windows vary with dose, frequency of use, metabolism, and hydration, so a negative result does not by itself prove that no exposure occurred.
