Delayed haemolytic transfusion reactions (DHTRs) are a recognized sequel of blood transfusion. The true incidence and importance of this complication have been difficult to estimate due to the lack of any prospective studies. We have carried out such a study by testing 530 patients who were transfused during cardiac surgery. 2% of the patients had new red cell alloantibodies detectable 1 week following transfusion. Despite this finding, and the fact that at the time the study was performed pre‐transfusion antibody screening of recipients was not routine practice, no DHTRs were diagnosed on clinical or laboratory criteria. These results indicate that the reported incidences, based on retrospective recognition of DHTRs, are not a serious underestimate of the frequency of the complication.
