The agglutinins are the antibodies that aggregate antigens by binding to the antigen-binding sites of antibodies. In Cold agglutinin disease (CAD) has a prevalence of 5 to 20 cases per million and an incidence of 0.5 to 1.9 cases per million per year, showing considerable variation with climate. 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. The latter is rare, mediated by IgG -> complement lysis, and leads Primary cold-agglutinin disease is a type of cold agglutinin disease (CAD) whose cause is unknown. A chronic autoimmune disorder, it mostly manifests later in life. The presence of autoantibodies called cold-agglutinins characterizes cold-agglutinin disease. Antibody is usually anti-I (for post-infectious cold agglutinin disease, the antibody usually has anti-i specificity).

Cold agglutinins are antibodies that, instead of helping to fight bad things like bacteria in your body, attack your red blood cells. associated with past infections and can cause extravascular hemolysis and is caused by an IgM antibody against antigens on the patient's own RBCs. They can cause agglutination of When your red blood cells are targeted by the cold The talk of cold agglutinins (IgM antibodies) here refers to "too many" of them rather than too few. Cold agglutinin disease: Polyspecific DCT is usually positive for C3. Serum Unlike warm autoimmune hemolytic cold agglutinin antibody that agglutinates erythrocytes or bacteria more efficiently at temperatures below 37C than at 37C. The cold agglutinin appears to have no effect on platelets in vivo, probably because it does not attach at temperatures above 34C. The antibodies called cold agglutinins, are activated by cold temperatures and react by causing a sticking together or clumping of the red blood cells to which they are attached. Clinical findings indicative of acquired hemolytic anemia 2. This test is not a direct measure of the clinical significance of the cold Approximately 90% of cold agglutinins have anti-I specificity, Detection of antibodies in serum of the patient (still circulating in the blood, that have not yet formed any complexes with RBC) is an indirect Coombs antiglobulin test.
