ABSTRACT
Abnormal haemoglobins lead to significant morbidity and mortality. This is a prospective study, evaluating types of haemoglobin and haematological parameters in blood samples of 631 Sudanese patients. Participants were patients who attended different departments in Khartoum Teaching Hospital in the period from March 2005 through July 2005. Electrophoresis was used to determine the type of haemoglobin. 585 cases have normal haemoglobin [Hb A]. Mean red cell indices were: Hbl 1.5 g/dl, PCV 34.9%, MCV 85.4 fl, MCH 32.1pg, MCHC 33.2 g/dl, RDW 37 fl and WBC 7013 /cm3. 46 [7.3%] patients had abnormal Hb. The frequency of Hb types were AA: 92.7%, AS: 4.9%, SS: 0.8%, AC: 0.5% and AF: 0.5%.The presence of abnormal haemoglobin such as haemoglobin S is not unexpected because we live in the centre of an affected area. The study showed low haematological parameters due to various causes including poor nutrition as well as infections and haemolytic processes
