HAEMATOLOGICAL STUDY OF ß-THALASSAEMIA AMONG IRAQI POPULATION

Blood samples of 80 clinically thalassaemic patients were collected from three thalassaemic centres in Iraq, in addition to 56 apparently healthy individuals were collected as a control group. Haematological examinations were applied for some parameters. The blood groups were determined for all samples, the relationships between blood groups and both gender and phenotypes of β-thalassaemia were studied. The results showed that there were no significant relationship at (p 0.05) between blood groups and both parameters (gender and phenotypes) for patients in comparison with the control group. The estimations of Hb concentrations, quantitative and qualitative Hb analyses by Hb electrophoresis in order to determine the Hb types (HbF, HbA, and HbA2) and reticulocyte count, were adopted for 31 β- thalassaemic patients and 20 apparently healthy individuals. According to the haematological examinations data, the relationships of gender, blood groups, and phenotypes with Hb concentrations, Hb types, and reticulocyte count were studied.
