WebIn cold agglutinin disease, certain abnormal bone marrow cells produce antibodies called cold agglutinins, which activate a part of the immune system known as the complement pathway. This activation results in the constant destruction of red blood cells, known as hemolysis. • The cold agglutinin antibody mistakenly attaches to a red blood ... WebPatients responded to transfusion with a median Hb increment per unit of 1.0 g/dL. RBC agglutination was seen in all cases without associated change in Hb, lactate dehydrogenase, bilirubin, or reticulocyte count.
