Expression of genetic markers of erythrocyte immunoglobulin G autoantibodies in autoimmune hemolytic anemia.

abstract：BACKGROUND AND OBJECTIVES:It is sometimes difficult to obtain antigen-negative red blood cells (RBCs) for patients with antibodies against RBCs. However, the frequency and severity of the adverse reactions have not been well elucidated. Here, we conducted a multi-institutional collaborative study to clarify the backgro...
