Cold agglutinin disease is a rare type of autoimmune hemolytic anemia in which the body's immune system mistakenly attacks and destroys its own red blood cells.When affected people's blood is exposed to cold temperatures (32º to 50º F), certain proteins that normally attack bacteria (IgM antibodies) attach themselves to red blood cells and bind them together into clumps (agglutination). It occurs when the body destroys red blood cells faster than it can make new ones. doi: 10.1016/j.exphem.2019.09.021.
