Introduction: Anaemia is an important nutritional problem affecting pregnant women in particular. It is the most important single cause of maternal mortality and also for various related abnormalities. Efficient diagnostic modalities which can be used for prediction of anaemia in a cost–effective manner are necessary. Aims: To determine and compare the usefulness of red cell distribution width (RDW) and red cell indices in prediction of anaemia in pregnant women. Materials and Methods: 180 pregnant women were included in this study. Haemoglobin level of less than 11.0 g/dl was considered for diagnosis of anaemia. Statistical correlation between RDW and red cell indices was calculated. Results: A significant statistical correlation was obtained between changes in haemoglobin level and RDW and mean corpuscular volume (MCV). The correlation between changes in haemoglobin level and RDW was statistically most significant. Conclusion: RDW is a better indicator for prediction of anaemia in pregnant women than red cell indices.
