Resumo: | Introduction: Iron deficiency anemia and thalassemia minor are microcytic and hypochromic types of anemia commonly found in our environment. The correct differentiation between them is of great clinical importance, although it is often hampered by the coexistence of diseases that may alter the results of standard tests for their discrimination, in addition to the significant costs of such tests. Objective: The objective of this study was to investigate the discriminatory power of red cell distribution width (RDW) between iron deficiency anemia and thalassemia minor. Method: Blood parameters were compared in 227 patients with iron deficiency anemia and/or thalassemia minor after diagnosis confirmed by molecular biology and HbA2 measurement for alpha thalassemia and beta thalassemia trait respectively. The frequency of alpha thalassemia trait in a population from two public hospitals of Minas Gerais was also determined. Result and conclusion: RDW was able to differentiate iron deficiency anemia from thalassemia trait, what indicates that this blood count parameter is a useful tool since concomitant disorders are excluded. In addition, a high frequency of the -α3.7 mutation was observed in the study population (20.3%), justifying its investigation when another cause for microcytic anemia is absent. |
