Cold-associated symptoms rarely appear, and the cold antibody may have a low antibody titer (eg, <1:64) but with a thermal amplitude up to 30 to 37°C. It can be diagnosed with a DAT positive for IgG and C3d, a cold antibody with a thermal amplitude ≥ 30°C, and an appropriate clinical picture. WebAt the cooler temperature, the cold agglutinin antibodies on the surface of red blood cells cause the cells to clump together, and it becomes more difficult for them to travel through the blood vessels. Acrocyanosis then develops, in which the skin in the peripheral areas of the body turns blue or purple.
