Accuracy of 25-hydroxyvitamin D assays: confronting the issues

TL;DR: If confirmed, these results suggest that most routine LC-MS/MS assays are perhaps overestimating 25-OHD by failing to resolve a molecule having the same mass as 25- OHD(3) and a similar fragmentation pattern.
Journal ArticleDOI

25-Hydroxyvitamin D: A Difficult Analyte

TL;DR: The history of 25-OHD methodology could serve as a case study of the consequences of transferring a rigorous but labor-intensive method from the unhurried atmosphere of the research laboratory to the bustle of a routine clinical laboratory having to meet tight deadlines.
Journal ArticleDOI

25-Hydroxyvitamin D assays: the quest for accuracy.

TL;DR: The recently reported difficulties experienced by Quest Laboratories have once again highlighted concerns about the reliability of 25-hydroxyvitamin D results, particularly those generated by liquid chromatography–tandem mass spectrometry (LC-MS/MS), the method used by Quest.
Journal ArticleDOI

Proficiency testing of 25-Hydroxyvitamin D (25-OHD) assays

TL;DR: A gas chromatography-mass spectrometry (GC-MS) reference method for 25-OHD is under development and will be used to assess whether the ALTM remains the most appropriate target for DEQAS samples.
