Simultaneous determination of vitamin D metabolites 25(OH)D and 1α,25(OH)D in human plasma using liquid chromatography tandem mass spectrometry.

Background: Although measurement of 25(OH)D is a routine analytical method to determine plasma vitamin D status, 1α,25(OH)D is the biologically active form. Hence, simultaneous measurement of 25(OH)D and 1α,25(OH)D could provide better insight into vitamin D status and pharmacokinetics. However, 1α,25(OH)D has a low plasma concentration, making its quantification challenging for most analytical techniques.
