agglutination
Let an agent explain agglutination, relay mechanisms, laboratory tests, blood typing and clinical relevance from immunology and transfusion medicine sources, describe the named forms, and distinguish agglutination from precipitation of soluble antigens, coagulation or blood clotting, rouleaux formation and the linguistic sense of agglutination.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
The clumping together of particles such as cells, bacteria or latex beads when antibodies or other binding molecules link them, used in blood typing, where antibodies against A or B antigens make red cells clump, in haemagglutination assays, including viral haemagglutination, in which viruses such as influenza bind red blood cells, in the haemagglutination inhibition test used to measure antibody responses, and in latex agglutination tests for infections; sperm agglutination, clumping of sperm sometimes caused by antisperm antibodies, is studied in fertility assessment. In transfusion, incompatible blood causes agglutination and haemolysis, which is why crossmatching is essential.
Why it exists Filled
