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. 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.
