WebbCold agglutinin disease (CAD) is a rare autoimmune disease characterized by the presence of high concentrations of circulating cold sensitive antibodies, usually IgM and autoantibodies that are also active at temperatures below 30 °C (86 °F), directed against red blood cells, causing them to agglutinate and undergo lysis.

WebbIn cold antibody disease, C3 is present while IgG is usually absent. The test is ≥ 98% sensitive for autoimmune hemolytic anemia; false-negative results can occur if antibody density is very low or, rarely, if the autoantibodies are IgA. WebbThe antigen I is but feebly developed at birth, judged by the weak reaction of cord cells with anti-I. The red cells of Mr. M. enabled the antibody in the serum of each of the eight available cases of acquired haemolytic anaemia of the cold antibody type and the antibody previously called “non-specific cold agglutinin” to be identified as anti-I. Cold sensitive antibodies (CSA) are antibodies sensitive to cold temperature. Some cold sensitive antibodies are pathological and can lead to blood disorder. These pathological cold sensitive antibodies include cold agglutinins, Donath–Landsteiner antibodies, and cryoglobulins which are the culprits of cold agglutinin disease, paroxysmal cold hemoglobinuria in the process of Donath–Landsteiner hemolytic anemia, and vasculitis, respectively. bruce pearl daughter bachelor
