ABSTRACT
Background: Blood groups are genetically determined and exhibit polymorphism in different populations. ABO and Rh blood groups are useful in population genetic studies, researching population migration patterns, as well as resolving certain medico-legal issues. Objective: The purpose of this study was to determine the Frequencies of ABO blood groups and Rh antigens among Sudanese Donors in Khartoum State. Materials and Methods: One Thousand samples were included in this study to determine the Frequency of ABO blood group and Rh phenotype among Sudanese Donors. ABO and Rhesus typing were carried out using monoclonal grouping anti-sera. Results: The results found that among 1000 Sudanese participants, 334 (33.4%) were A blood group, 149 (14.9%) were B blood group, 511 (51.1%) were O blood group and 6 (0.6%) were AB blood group. The Rhesus blood group was positive in 970 (97%) and negative in 3 (3%) among the study population. The frequency of RhC, Rhc`, RhE and Rhe` antigen were 299 (29.9%), 959 (95.5%), 146 (14.6%) and 978 (97.8%) respectively. Conclusion: The findings indicate that the ‘O’ was the most common ABO blood group and RhD, Rhc and Rhe are highly prevalent among the study population.
