• Autoimmune hemolytic anemia is caused by autoantibodies that react with red blood cells at temperatures ? 37� C (warm antibody hemolytic anemia) or < 37� C (cold agglutinin disease). Hemolysis is usually extravascular. The direct antiglobulin (direct Coombs) test establishes the diagnosis and may suggest the cause. Treatment depends on...
