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 image explains agglutination in the blood. Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare (glueing to).. Agglutination is a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps usually as a response to a specific antibody.
Rouleaux formation on wet smear. Rouleaux (singular is rouleau) are stacks or aggregations of red blood cells (RBCs) that form because of the unique discoid shape of the cells in vertebrates.
The direct and indirect Coombs tests, also known as antiglobulin test (AGT), are blood tests used in immunohematology.The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [1]
A latex fixation test, also called a latex agglutination assay or test (LA assay or test), is an assay used clinically in the identification and typing of many important microorganisms.
Autoimmune hemolytic anemia (AIHA) is an autoimmune disorder which occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to burst (), leading to an insufficient number of oxygen-carrying red blood cells in circulation ().
A slide coagulase test is run with a negative control to rule out autoagglutination. Two drops of saline are put onto the slide labeled with sample number, Test (T) and control (C). The two saline drops are emulsified with the test organism using a wire loop, straight wire, or wooden stick.
Secondary cold agglutinin syndrome occurs when autoantibodies bind to red blood cells, rendering them subject to attack by the complement system. [17] It is a result of an underlying condition potentially associated with either monoclonal cold-reacting autoantibodies or polyclonal cold-reacting autoantibodies [16] predominantly caused by infection or lymphoproliferative disorders.
