Hemoglobinopathies are most common inherited disorders in the world; approximately 7 percent of the worldwide population and 5-6 percent of population of Iran are carriers. The hemoglobin disorders inherit as autosomal recessive and are very common in the Mediterranean area and much of the Asia and Africa. The control of this inherited disorders need to genetic counseling and accurate screening by more advanced and more accurate methods. This study explains features of current Iran hemoglobin disorders, nominates the accessible methods for screening them and introduces the capillary zone electrophoresis as a rapid and more accurate method. The required data were extracted of various articles and then for good explanation, current Iran hemoglobinopathies properties were showed in the tables and electropherograms of important hemoglobin disorders in Iran population were provided for help to interpretation results of blood tests by capillary zone electrophoresis method. Hemoglobin disorders are including thalassemias and hemoglobin variants; Disruption in the production and malfunction of globin chains cause types of hemoglobin disorders. We cannot introduce one of clinical laboratory tests as critical and basic method for screening and distinguishing types of inherited hemoglobin disorders as alone. For distinguishing the types of them must be prepared enough information and data of the hemoglobin disorders and for more accurate analysis must be used simultaneously different methods as gel electrophoresis, high performance liquid chromatography, isoelectric focusing, capillary zone electrophoresis or molecular tests. The capillary electrophoresis is an accurate and rapid method for screening types of the hemoglobin disorders. Other side this method cannot analyze all of them, so must be used biochemical, biophysical and molecular methods for confirmation the results. This review showed we can use the capillary electrophoresis and HPLC as two complementary methods for hemoglobinopathies screening. We can analyze by the methods more hemoglobin disorders and decrease more laboratory errors. Moreover, we must have patient history, hematological indices, information and data of types of hemoglobinopathies. The patient history and complete blood count results as red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration can be useful and helpful in screening the hemoglobin disorders and then distinguishing all of hemoglobin disorders.
