Warm autoimmune hemolytic anemia (wAIHA) is an autoimmune condition in which red blood cells are destroyed prematurely, resulting in a decrease in the body's red blood cell count. wAIHA is referred to as warm because the antibodies that attach to red blood cells to cause their destruction are most active at normal body temperature.
Warm autoimmune hemolytic anemia (wAIHA) is an autoimmune condition in which red blood cells are destroyed prematurely, resulting in a decrease in the body's red blood cell count. wAIHA is referred to as “warm” because the IgG antibodies are active at normal body temperature which is not the case for other types of autoimmune hemolytic anemia.
