Lyse or not to lyse: clinical significance of red blood cell autoantibodies

Autoimmune hemolytic anemia (AIHA) is a rare autoimmune disease characterized by a hemolytic anemia caused by autoantibodies against red blood cells (RBCs). These autoantibodies are routinely detected via the Direct Antiglobulin Test (DAT). As expected, the DAT score correlates with the presence of clinical symptoms, but this correlation is far from perfect. Regularly, strongly positive DAT scores are encountered with no sign of hemolysis, while severe hemolysis can be seen even in patients with a negative DAT score.
