Abstract
The present invention provides a method and device for detecting the presence of binding ligands, especially blood group antigens or antibodies thereto, which utilize a matrix of substantially noncompressable microparticles, which matrix provides superior performance in allowing movement of nonagglutinated reactants, especially red blood cells, while constraining, preferably in a so-called 'band formation' agglutinated reactants, especially red blood cells.
