IDENTIFICATION METHODS AND COMPLICATIONS OF BLOOD GROUPS

Abstract

Post-transfusion reactions are observed in 0.002-0.2% of cases where incorrect  blood groups are transfused out of 6,000-29,000 blood transfusions. Fatal hemolytic reactions occur in 1 out of 100,000 blood transfusions, with 83% of them being due to incompatible reactions according to the ABO system. In the UK, 1 in 10 transfusions results in a fatal outcome, while in the US it is 1 in 18 and in Russia it is 1 in 3.9.
