Other names	WAIHA
Specialty	Hematology

Warm antibody autoimmune hemolytic anemia (WAIHA) is the most common form of autoimmune haemolytic anemia.^[1] About half of the cases are of unknown cause, with the other half attributable to a predisposing condition or medications being taken. Contrary to cold autoimmune hemolytic anemia (e.g., cold agglutinin disease and paroxysmal cold hemoglobinuria) which happens in cold temperature (28–31 °C), WAIHA happens at body temperature.^{[citation needed]}
