1. An assay card adapted for treating and analyzing a sample comprising:

  • a solid bottom plate having a top surface, a front end, a rear end and sides extending between said front and rear ends;

    a top plate having a bottom surface, a front end, a rear end and sides extending between said front and rear ends;

    a middle plate having a top surface, a bottom surface, a front end, a rear end and sides extending between said front and rear ends, said middle plate being sandwiched between said bottom and top plates so that said middle plate top surface is adjacent to said top plate bottom surface and said middle plate bottom surface is adjacent said bottom plate top surface;

    a sample slot in said middle plate adapted to receive and hold an assay rod, said slot extending from said middle plate top surface to said middle plate bottom surface, said slot defining an assay rod chamber located between said top and bottom plates;

    a flexible indentation in said top plate bottom surface extending away from said middle plate which defines a solution chamber between said top plate bottom surface and said middle plate top surface;

    conduit means betwen said solution chamber and assay rod chamber for providing conduits through which solution can be transferred between said assay rod chamber and said solution chamber; and

    means associated with said assay rod chamber for introducing said sample into said assay rod chamber to interact with an assay rod located therein, said flexible top plate being deformable towards said middle plate at said indented portion defining said solution chamber to force solution through said conduit means to provide transfer of solution between said assay rod chamber and said solution chamber to provide treatment of said assay rod with said solution.
