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 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 and internal standards from other plasma components by reverse-phase HPLC with quantitation by tandem mass spectrometry.(Unpublished Mayo method)
Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Friday
