Latex agglutination is defined as which phenomenon?

• A. agglutination of red blood cells
• B. agglutination of microscopic latex beads that have been covered with antigens
• C. color change in the solution
• D. formation of a precipitate

Answer: (B)

Latex agglutination refers to the clumping of tiny latex beads that have been coated with an antigen (or antibody). When a sample contains the corresponding antibody (or antigen), those binding interactions link multiple beads together, producing visible aggregates. This cross-linking creates a positive, easily seen result without the need for instruments. It’s distinct from red blood cell agglutination, color changes, or precipitate formation, which are different types of reactions.
