Method Name
Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)
Method Description
Opiates exist in patient urine as both free and either sulfate or glucuronide conjugates. Enzyme hydrolysis is used to liberate the conjugated drug. Specimens are then centrifuged, diluted, and filtered and the analytes are separated by liquid chromatography tandem mass spectroscopy and analyzed by multiple reaction monitoring.(Unpublished Mayo method)
