Nearly all red cell antibody identification cases referred to IRLs are straightforward, being single, multiple, or autoantibodies. But in a small percentage, antibody identification is challenging, requiring the most experienced and educated minds and the best resources for various serologic and molecular techniques. This session will review a few specific case studies to demonstrate the resolution challenging antibody investigations and provide recommendations for the most appropriate blood for transfusion. Complex immunohematology cases may involve unknown high-prevalence antibodies, complex transfusion and transplant histories, and the presence of RHD and RHCE antigen variants.
Learning Objectives:
Illustrate the process for test selection to effectively solve complex immunohematology cases
Design detailed differentials for the choices of test approaches and resources
Integrate multiple test results into a comprehensive antibody interpretation and transfusion plan
