Abstract: Objective To identify specific antibodies(allo-antibody and mimicking antibody)in patients with autoimmune hemolytic anemia(AIHA)by antibody titration procedure. Methods Samples from patients tested positive for direct antiglobulin test from the blood group reference laboratory of Shanghai Blood Center between March and April 2021 were collected. Serum,eluate and diluent eluate for antibody titers were used to identify antibodies. Results Four specific antibodies in serum,3 specific antibodies in eluate,9 specific antibodies in diluent eluate were detected. Conclusion The proportion of specific antibodies detected in diluent eluate in positive DAT patients were higher than that of serum and eluate. The antibody titers play a decisive role in eluate dilution. Testing for antibody titer can increase detection rate of mimicking antibody in AIHA patients. It can reduce the reduction of blood transfusion effect due to mimicking antibody to improve the safety and effectiveness of a transfusion.

Key words: Eluate Antibody titer, Allo-antibody, Mimicking antibody
