The ORTHO BIOVUE system column agglutination technology standardizes blood typing and compatibility testing in a 6-microcolumn cassette preloaded with diluent and/or reagent and glass beads. Test red cells, with or without serum, are placed in the chamber above the column. Upon centrifugation, red cells are forced through the bead column where agglutinated cells are trapped, while unagglutinated red cells travel to the bottom of the column, forming a discrete pellet.
