Iron supplementatıon ın pregnancy and ıts ımplıcatıons on hematologıcal parameters

İstanbul Polis Hastanesi, İstanbul.

Objective: To evaluate the effect of iron supplementation in pregnancy on hematological parameters.

Methods: Ninety-eight normal pregnant followed in obstetrics outpatient clinic, were assessed for hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), serum iron and iron binding capacity in a cross sectional study. Hematological characteristics of iron supplemented and non-supplemented pregnant were compared.

Results: When the two groups are compared by means of blood parameters; the iron supplemented group (n:63) showed higher MCV, serum iron and lower RDW and iron binding capacity than the non-supplemented group (n:35). No difference was observed on haemoglobin, haematocrit, MCH and MCHC values between the two groups.

Conclusion: Iron supplementation for two months in pregnancy showed statistically significant changes on MCV, RDW, serum iron and transferrin levels in this cross sectional study. These hematological parameters are thought to be more useful than hemoglobin and hematocrit on the hematological follow up of the supplemented pregnant. There is also need to reevaluate the laboratory normals for anemia definition.
