Question

The process by which antibodies clump bacteria or antigen-bearing cells together, as seen in blood typing reactions, is called:

Options

• Precipitation

• Complement fixation

• Opsonisation

• Agglutination

Answer 1

Agglutination is the antibody function that clumps bacteria or antigen-bearing cells together. This process is particularly important in blood typing reactions, where IgG and IgM antibodies bind to antigens on red blood cells, causing them to aggregate and precipitate.
