WebIn-saline agglutination test specificity can be increased by adding saline washing steps before assessing for agglutination. 9 Because RBC agglutination does not occur in many IMHA patients, a negative in-saline agglutination test result does not rule out IMHA. FIGURE 5. In-saline slide agglutination test process. In hematology, red cell agglutination or autoagglutination is a phenomenon in which red blood cells clump together, forming aggregates. It is caused by the surface of the red cells being coated with antibodies. This often occurs in cold agglutinin disease, a type of autoimmune hemolytic anemia in which people produce antibodies (termed cold agglutinins) that bind to their red blood cells … WebKey Points. Autoimmune hemolytic anemia is caused by autoantibodies that react with red blood cells at temperatures ≥ 37 ° C (warm antibody hemolytic anemia) or < 37 ° C (cold agglutinin disease). Hemolysis is extravascular. The direct antiglobulin (direct Coombs) test establishes the diagnosis and may suggest the cause. can hydrogen have a negative charge
