Maternal serum folacin levels decrease during pregnancy. This decrease could not be explained by hemodilution. Postpartum levels did not increase significantly compared to values measured at partum. In a healthy Dutch pregnant population receiving no vitamin supplementation the folacin status is at risk and after pregnancy it takes considerable time to refill folacin stores.
孕期母体血清叶酸水平会下降。这种下降无法用血液稀释来解释。与分娩时测得的值相比，产后水平没有显著升高。在未补充维生素的健康荷兰孕妇群体中，叶酸状态存在风险，且产后需要相当长的时间来补充叶酸储备。
