Development and Validation of a Novel Ultraperformance Liquid Chromatography-Tandem Mass Spectrometry Method for Serum 3-Epi-25-Hydroxyvitamin D 3 , 25-Hydroxyvitamin D 3 , and 25-Hydroxyvitamin D 2

Background: The epimeric form of 25-hydroxyvitamin D3 (3-epi-25-hydroxyvitamin D3, 3-epi-25-OH-D3) can interfere with the accurate measurement of total vitamin D. Therefore, reliable quantification of epimeric metabolites is important for improving measurement accuracy.Here, we d...
