Immunological studies in a case of Evans' syndrome

Immunological studies in a case of Evans' syndrome (autoimmune hemolytic anemia of the "warm type" associated with idiopathic thrombocytopenic purpura) are presented in whom the autoimmune nature of both conditions was verified by the demonstration of cell-bound and free serum autoantibodies against red blood cells as well as platelets by a radioimmune technique.
