Determination of serum ferritin in nomal term pregnant women and newborns and its significance.

【Objective】 To study their relations in iron storage in mothers and their newborns. 【Methods】 To determine serum ferritin(SF) in 260 cases of nomal term pregnant women in labor and paired newborns.According to the iron supplementation,they were divided into 2 groups:non-iron supplementation and iron supplementation groups.The data of serum ferritin was analysed. 【Results】 The SF levels of newborns were sighificantly higher than those of maternal levels(P0.01).There was a significant correlation in serum ferritin both pregnant women and newborns(r=0.78,P0.01).The serum ferritin levels of non-iron supplementation groups in labor were sighificantly lower than those in middle trimester pregnant women.The serum ferritin levels of pregnant women of iron supplementation groups were sighificantly higher than those of the non-iron supplementation groups in labor(P0.01). 【Conclusion】 The serum ferritin screening of pregnant women and newborns is early performed,and according to the serum ferritin levels,the iron supplementation is given in time,the iron deficiency of pregnant women and newborns can be effectively prevented and treated.
