Feedback.25 mL) Serum separator tube or plain red. In this syndrome, cold agglutinins, usually IgM with anti-I specificity, attach to the patient's erythrocytes causing a variety of symptoms. These antibodies are called agglutinins because they bind multiple 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. Autoimmune hemolytic anemias (AIHAs) are a collection of disorders characterized by the destruction of RBCs through antibody-mediated hemolysis (extravascular and/or intravascular). (Min: 0. In the case of AIHA, the body’s immune system attacks and destroys its own red blood cells. The definition of agglutination is the clumping together of blood cells. Dalam mikrobiologi dan imunologi, istilah aglutinasi terutama merujuk pada sel bakteri yang menggumpal dengan adanya antibodi atau komplemen.

CR Cold agglutinin disease is rare, with an estimated incidence of approximately 1 per million. Cold agglutinins are active at cold temperatures. C1 esterase activates C4 and C2, generating C3 convertase, which binds and splits C3, leading to deposition of C3b on the cell surface. Contoh-contoh dari aglutinin adalah antibodi dan lektin.
