Amniotic fluid levels of 25-hydroxyvitamin D3 and 24,25-dihydroxyvitamin D3

Vitamin D3metabolites in amniotic fluid in relation with maternal and fetal sera in term pregnancies

“…The amniotic fluid level of 25(OH)D 3 and 24,25(OH) 2 D 3 in this study are lower than those we have published previously and in agreement with the findings of LASEBNIK, et al [20] (figures 1 and 2). Our data, at that time [23] were obtained by another assay method [13] which has since shown to produce higher than average results [26]. Amniotic fluid levels of 1,25(OH) 2 D 3 are shown in figure 3.…”

“…The maternal and cord sera levels of these metabolites were not yet correlated with another important compartment -the amniotic fluid. In the past, we have determined amniotic fluid levels of 25(OH)D3 and 24,25(OH)2D3 during pregnancy [23]. However, the source of the amniotic fluid vitamin D3 metabolites remained unclear.…”
