Distribution of ABO Blood Groups in a Tertiary Care Centre in North-Eastern, Nigeria
Abstract
Background: ABO blood group antigens are hereditary, and are the most important compatibility test in any blood transfusion service. These antigens are also important in genetic studies, and in resolving medico-legal issues. It is important to determine the ABO blood group in blood banking and transfusion medicine. There is no data on the distribution of the ABO blood group in our centre. We therefore determined the distribution of the ABO blood group among voluntary blood donors at the Federal Medical Centre, Yola, Nigeria.
Study design and duration: The study was a hospital-based cross sectional study, and was carried out at the blood bank of Federal Medical Centre, Yola, Nigeria from January, 2007 to December, 2008.
Methodology: Five hundred and ninety five consecutively recruited voluntary blood donors had their ABO blood group done using the Slide method, and confirmed with the Tube method. The biodata of the patients were obtained. Written informed consent was obtained from each patient.
Results: Of all the patients tested, 571 donors (96%) were males while 24 (4%) were females. The mean age was 31.3+/- 7.9 years. Blood group O was the most frequent with 82.2%, group B 9.2%, group A 7.9% while group AB was 0.7%.
Conclusion: The most frequently encountered ABO blood group was O, while AB was the least. There is no sex predilection in the distribution of ABO blood group.
