#agglutination

• Agglutination — The act of agglutinating or clumping and its result; the adhesion, union, or grouping of suspended particles. In immunology, it represents the specific reaction where antibodies cause the clumping of bacteria or erythrocytes, while in linguistics it is the welding of lexical and grammatical morphemes into a single word.
• Agglutination — A less frequent linguistic variant of the noun 'aglutinare', used historically or in certain academic works to describe the phenomenon of binding, welding, or clumping of discrete elements. In linguistics, it represents the union of morphemes, while in biology, the grouping of cells or bacteria under the action of antibodies.
• Autoagglutination — A spontaneous biological or immunological phenomenon in which blood cells (especially erythrocytes or platelets) in a sample cluster and clump together on their own, as a result of the direct reaction between membrane antigens and specific autoantibodies present in their own serum, without the addition of an external reagent; a clinical test relevant for diagnosing autoimmune hemolytic anemias.
