Auto Immune Hemolytic Anemia are acquired disorders where auto-antibodies develop against one’s own red blood cells and haemolysis results from their increased destruction. Auto immune haemolytic anemia are divided into warm or cold types depending which temperature the antibody binds itself to the red cell.

Warm auto immune anemia occurs at all ages though more in adults. Both sexes are involved though disease is more common in females. Compared to this form, cold auto Immune Hemolytic Anemia is a disease involving adults beyond 50 years of age.
