Anemia is the most common blood disorder encountered in pregnancy and affects approximately 38% of pregnant women globally. Iron deficiency anemia (IDA) continues to be the commonest etiology of anemia in pregnancy. The prevalence of iron deficiency (ID) in pregnant Indian women is amongst the highest in the world. The development of iron deficiency anemia is associated with increased risk of preterm births and low birth weight infants. IDA is characterized by microcytosis, (low MCV<80fl) and hypochromia(MCH<27pg) and blood film may confirm characteristic microcytic cells or pencil cells. While IDA is the commonest cause for decreased MCV, low MCV is insensitive and upto 40% of pregnant women with true IDA have normocytic indices. Stimulation of erythropoiesis in pregnancy masks the microcytosis of iron deficiency. A prospective observational study was performed on 100 pregnant women at Baraut, Medicity Hospital, Baghpat UP,India where 50 women were anemic and the results recorded the significant level of abnormal in all hematological parameters compared with 50 non anemic pregnant women and the significance was given as student’s test (p<0.001)
