Immunological agglutination assays with dyed or colored latex and kits

摘要

Latex agglutination test methods and kits. Employing dyed latex polymer particles and adding a water-soluble, non-latex polymer particle absorbing dye contrasting in color to the dyed latex polymer particles produces a reaction mixture that changes color when agglutination occurs. Direct and indirect latex agglutination tests are contemplated which are useful in detecting disease states or physiological states such as pregnancy.
