A Transfusion Experience for a Patient with Cis-A2B3 Phenotype / 대한수혈학회지

ABSTRACT

We report the case of a 64-year-old man presenting to the hospital for treatment of his anemia. Exact ABO blood typing is an essential step to prevent transfusion reactions. The selection of the wrong blood component for transfusion can be a clinical problem and in this case the patient had a cis-AB blood type that could have caused an ABO discrepancy. In this case neither autologous or directed blood transfusion was possible and O+ red blood cell was transfused without a transfusion reaction.
