Which is a characteristic of warm antibody immunohemolytic anemia?

Warm antibody immunohemolytic anemia occurs when antibodies bind to the surface of red blood cells at body temperature (hence the term "warm") and the bound cells are removed from circulation by macrophages in the spleen. It is not gender-specific and can occur in both men and women. Hemolysis can occur and the anemia may require treatment. IgM typically coats erythrocytes in cold agglutinin disease, not warm antibody immunohemolytic anemia.
