Non specific cold antibody
WebbThe autoantibody is a biphasic hemolysin that binds RBC at 0°C to 4°C but does not activate complement until warmed to 37°C. The DAT is positive for C3d and negative for IgG. The diagnosis is confirmed by a Donath-Landsteiner test.

WebbWestern blotting is used to check that the antibody is detecting a protein of the right size. Multiple bands on a Western blot suggest non-specific antibody binding. Antibody specificity can be checked by pre-incubation of the primary antibody with the antigenic peptide (an adsorption test). 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.
WebbDuring preoperative screening, all initial preoperative routine test results were normal, except for the presence of the non-specific cold antibodies confirmed by the saline method. The direct antiglobulin test was negative for anti-immunoglobulin G, but we did not perform further testing of anti-C3.
