SUMMARY THE IMPORTANCE OF PROPHYLACTIC IRON ADMINISTRATION IN PREGNANCY This prospective study was made on 32 pregnant women, who were found to be non-anemic according to the hematologic parameters measured between the 28-32nd weeks of the pregnancy. Iron therapy was given to 16 pregnant women, who were chosen as experiment group, who had an average of 8.62 ± 6.55 weeks until delivery. No treatment was given to the 16 pregnant women chosen as control group. In the hematologic parameters measured during delivery a significant increase of serum ferritin in experiment group, compared to the level measured in pretratment, was found (p0.05). The average serum ferritin level of the'new born babies of experiment group was found higher than the new born babies of the control group ( p 0.05). Denek grubu¬nun yeni doğan bebeklerinde, serum ferritin düzeyi ortalaması, kontrol grubunun bebeklerinin serum ferritin düzeyi ortalama¬sından daha yüksek bulundu (p
