Patent ID: 8187538

Claim:
An immunodiagnostic test card for use in an immunodiagnostic testing apparatus, said test card comprising: a substantially flat planar substrate defined by an upper end and a lower end; a plurality of vertically disposed chambers supported within the upper end of said substantially flat substrate, said plurality of chambers including a linear array of reaction chambers, each said reaction chamber initially containing a quantity of a test material capable of producing an agglutination reaction when a patient sample is added and mixed therewith in said testing apparatus, said test material including at least one of beads and gel material to enable separation of agglutinants for the detection thereof; and said plurality of chambers further including a plurality of dilution chambers supported in the upper end of said substrate, said plurality of dilution chambers including at least one pair of dilution chambers disposed in side by side relation between at least one pair of adjacent reaction chambers, said at least one pair of dilution chambers being parallelly arranged in a direction that is substantially perpendicular to the linear direction of said reaction chambers and wherein said pair of dilution chambers are each sized to fit within the linear array defined by said reaction chambers.
