Hemagglutination is defined as which of the following?

• A. A form of agglutination involving red blood cells
• B. A type of protein synthesis
• C. A test using latex beads
• D. A method of measuring white blood cells

Answer: (A)

Hemagglutination is the clumping of red blood cells caused when antibodies bind to antigens on the surface of those cells, cross-linking them into visible aggregates. This happens in blood typing tests when antibodies against A or B antigens recognize and bind RBCs that carry those antigens, leading to a visible clump if the antigen is present. It’s specifically about red blood cells, not proteins being made, not latex-bead tests, and not counting white blood cells.
