WebNational Center for Biotechnology Information Web5 mrt. 2024 · Agglutination of red blood cells is called hemagglutination. One common assay that uses hemagglutination is the direct Coombs’ test, also called the direct antihuman globulin test (DAT), which generally looks for nonagglutinating antibodies. The test can also detect complement attached to red blood cells.
