Investigation of cold agglutinins


Test Background
Cold agglutinins are autoantibodies that react with antigens on the red blood cell surface. They may induce complement-mediated haemolysis and agglutination (clumping) of red cells (a cryopathic haemolytic syndrome), causing haemolysis and red cell destruction in the reticuloendothelial system or the agglutination of red cells in peripheral cold-exposed vessels leading to vaso-occlusion.


Clinical Indications
This test can sometimes be helpful when a cold autoantibody is suspected, but the diagnosis can often be made from examining a blood film without any complex serological testing.
