BACKGROUND Rapid, easy and reliable measurement of the major vitamin D metabolites is required in order to fulfill the needs of a clinical routine laboratory. To overcome these challenges, we have developed and validated a LC-MS/MS method for the quantification of 25-hydroxyvitamin D2 and D3, epi-25-hydroxyvitamin D3 and 24,25-dihydroxyvitamin D3. METHODS Sample preparation was based on preci...
