Abstract: When red blood cells carrying one or both ABO antigens are exposed to the corresponding antibodies, they agglutinate (clump together). People usually have antibodies against those red cell antigens that they lack. This research work is therefore embarked upon to know the frequency of ABO blood groups among blood donors in Ado-Ekiti and its metropolis. 7242 subjects who visited the Blood Bank of Ekiti State University Teaching Hospital, Ado-Ekiti between January 2009 and October 2014, to donate blood either as relative donors, voluntary donors or commercial donors were recruited for this study. 4ml of blood was collected into plain bottles from each Subject. Cells and sera grouping were subsequently carried out after clot retraction. Blood Group O has the highest frequency (73.04%) followed by group A (13.42%) and then group B (13.12%) while group AB has the least frequency (0.41%). The highest frequency of blood group O is due to the ability of group O individuals to donate to other blod groups other than group O and also the fact that group O is the commonest blood group. Male donors were more than the female donors which could be due to low haemoglobin level in females, other inclusion criteria like; absence of menstruation, lactation, pregnancy etc, and the fears usually exhibited by females to donate blood as a result of lack of adequate awareness on the importance of blood donation. Blood Transfusion Professionals should therefore take blood donation awareness as part of their duties.
