摘要: The demand for vitamin D analysis in veterinary species is increasing with the growing knowledge of extra-skeletal role plays health and disease. circulating 25-hydroxyvitamin-D (25(OH)D) metabolite used to assess status, benefits analysing other metabolites complex pathway are being discovered humans. Profiling by liquid chromatography tandem mass spectrometry (LC-MS/MS) facilitates simultaneous multiple a single sample over wide dynamic ranges, this method now considered gold-standard quantifying metabolites. However, very few studies report using LC-MS/MS species. Given complexity similarities roles disease between humans companion animals, there clear need establish comprehensive, reliable that comparable human clinical practice. In review, we highlight differences metabolism measuring beyond 25(OH)D. Finally, discuss analytical challenges profiling focus on methods.
