Deuterated stable isotopes are added to sample as internal standard. 1,25-Dihydroxyvitamin D and the internal standard are extracted. The extracts are then further purified by solid phase extraction (SPE) and affinity extraction. Extracts are then derivatized and analyzed by chromatography-tandem mass spectrometry using multiple reaction monitoring.(Unpublished Mayo method)
