Patent ID: 8735142

Claim:
An apparatus for immunologically analyzing a sample for at least one analyte, the apparatus comprising: at least one well comprising structural elements defining an internal volume, structural elements defining a well wall surface area, and structural elements defining a detection aperture, the well wall surface area obscured from view through the detection aperture; a plurality of scavenger antigens bound to the well wall surface area structural elements of the at least one well; at least one test fluid comprising a plurality of tagged antibodies; means for introducing the plurality of tagged antibodies into the at least one well; at least one sample fluid comprising a plurality of target antigens; means for introducing the plurality of target antigens into the at least one well to form a combined solution with the plurality of tagged antibodies; means for retaining the combined solution of the plurality of target antigens and the plurality of tagged antibodies within the internal volume of the at least one well; and means for detecting tagged antibodies bound to target antigens suspended in the internal well volume through the detection aperture.
