Fentanyl is a potent, short-acting synthetic opioid analgesic. Fentanyl is measured in blood and urine following mixed-mode solid phase extraction. The specimens are fortified with deuterated internal standard and a five-point calibration curve is constructed. The final extracts are reconstituted in methanol and analyzed using selected ion monitoring gas chromatography-mass spectrometry.
