The Architect 25(OH)D assay showed an intra‐ and inter‐assay imprecision of <5%.Comparison of the Architect assay with the LC ‐ MS / MS method showed a good correlation in both vitamin D‐insufficient and vitamin D‐supplemented subjects, however, with a negative mean bias of 17.4% and 8.9%, respectively. Jun 15, 2018 · The biologically active form of vitamin D, 1,25(OH) 2 D3, binds to the vitamin D receptor (VDR) in normal breast epithelium and this complex regulates the cell cycle, promotes differentiation, increases cell-to-cell adhesion, protects cells from DNA damage, regulates cytokines, activates immune cells, and suppresses inflammation, all of which Apr 9, 2023 · A serum level of 25-hydroxyvitamin D (25 OH D) of at least 30 ng/ml (78 nmoL/L) is required to maintain the physiologic function of vitamin D. Recommendations are to use 25-hydroxyvitamin D (25 OH D) as a measure of vitamin D status as it has a half-life of 2 weeks; whereas, 1,25-dihydroxy vitamin D (1,25 (OH)), the biologically active form Many tissues have vitamin D receptors, and some convert 25 (OH)D to 1,25 (OH)2D.

However, due to its lipophilicity and very low circulating concentration, the Oct 19, 2023 · Conclusions: D3 leads to a greater increase of 25(OH)D than D2, even if limited to daily dose studies, but D2 and D3 had similar positive impacts on their corresponding 25(OH)D hydroxylated forms. BMI should be considered when comparing the effect of daily vitamin D2 and vitamin D3 supplementation on total 25(OH)D concentration. 6ndr.
