ABSTRACTA haemolytic transfusion reaction includes signs of red cell destruction following transfusion. Haemoglobinuria and jaundice are the most frequent. We carried out a retrospective study to determine the frequency of red phenotype cells in a multitransfused patient population who needed specific compatible red cells . In the course of screening tests we found that the frequency of the different erythrocyte antigens varied widely among the different groups of donors compared with patients from Mexico: ABO System, O Group = 72.0% vs 62.6%, Rh System = R1R1 = 26.4% vs 31.69%, R2R2 = 6.9% vs. 7.8% Rh negative = 2.9% vs 4.8%, Duffy-a = 15.0% vs 21.0% and Kidd-a = 18.0% vs 27.55. These results allow us to detect the relatively high frequency among patients compared with the donor population.
