Immunological color change test involving two differently colored reagent spots |
摘要 |
A method and device for detecting an antigenic material in which the device comprises a test utensil having an indentation in which two reagent spots are placed, the first body being a dyed substrate having a coating of an antibody or antibody-like material thereon and the second of the two reagent spots comprising a dyed test-inert material or a dyed substrate with a coating of a normal animal serum, the dye employed in the second reagent spot having a different color than that employed in the first spot. When a liquid test sample is added to the indentation, the dyed substrate particles or components are suspended or solubilized, and the resulting suspension gives the appearance of a third color. A positive agglutination test is indicated by the formation of at least one spot having the color of the first dyed substrate against a background having the color of the second dyed substrate.
