#cell clumping

• 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.
• Agglutinin — A specific antibody or protein substance present in blood plasma or immune serum, capable of inducing the process of agglutination (clumping together) of foreign cells, bacteria, erythrocytes, or antigen-bearing particles. It plays a fundamental role in blood typing and in the immune defense mechanisms of the organism.
• Agglutinoscope — A laboratory optical device or instrument used for the examination, visual amplification, and precise determination of fine macroscopic or microscopic agglutination reactions. It facilitates the rapid reading of results in hemagglutination, immunology, or microbiology tests, allowing the observation of barely noticeable cell clumps.
