Approaches against the interference of autoantibodies with pre-transfusion compatibility testing / 中国输血杂志

ABSTRACT

Pre-transfusion compatibility testing is complicated in autoimmune hemolytic anemia (AIHA) patients due to the presence of autoantibodies. Delays in blood transfusion or even life-threatening would occur if blood type, isoantibodies/ autoantibodies of these patients could not be correctly identified to choose the appropriate blood components. Knowing the detection and treatment countermeasures against blood transfusion compatibility in AIHA patients is of great significance to ensure the timeliness and safety of blood transfusion. Based on the research progress at home and abroad, this article summarizes the serological characteristics, autoantibody types, blood group identification methods, antibody screening and antibody identification methods, and blood transfusion strategies about AIHA patients, in order to eliminate the interference of autoantibodies and provide transfusion guidance for the staff of Blood Transfusion Department.
