Prevalence of Anti- A and Anti – B Haemolysins among blood group ‘O’ donors in Makurdi, Nigeria

Blood group O donors are “inappropriately” called universal donors. These donors could become potentially “dangerous” if haemolysins are detected in their plasma. This study determined the prevalence of anti–A and anti–B haemolysins among blood group O donors in Makurdi, Benue State. Three hundred and five voluntary group O donors were screened for anti–A and anti–B haemolysins using the standard tube technique and samples showing haemolysis were titrated for anti A and anti B haemolysins. The overall prevalence of anti–A and/or anti–B haemolysins was 66.2%. Prevalence of anti–A haemolysins was 6%, anti–B haemolysins 14%, and both was 45.6% of blood donors.
