Test ID: PLP    
Pyridoxal 5-Phosphate (PLP), Plasma

Method Description Describes how the test is performed and provides a method-specific reference

The stable isotope pyridoxal 5-phosphate-d2 and/or pyridoxic acid-d2 is added to plasma as an internal standard. Meta-phosphoric acid solution is then added to precipitate the proteins. Following sedimentation of the proteins, an aliquot of the clarified supernatant fluid is subjected to separation of pyridoxal 5-phosphate, pyridoxic acid, and internal standards from other plasma components by reverse-phase HPLC with quantitation by tandem mass spectrometry (LC-MS/MS).(Unpublished Mayo method)
