Patent ID: 8715590

Claim:
A lateral flow and flow thru assay device comprising: a) at least two membrane analyte assay substrates positioned in parallel rows in different planes; b) a plurality of fluid flow channels within each of said two membrane analyte assay substrates; c) at least one lateral flow and flow thru assay embedded in each of said fluid flow channels; d) at least one test sample pad on each of said membrane analyte assay substrate, said at least one test sample pad receiving and transferring said at least one test sample fluid to said plurality of flow channels and at least one lateral flow assay and flow thru assay on each of said membrane analyte assay substrates; (e) at least one contiguous fluid flow manifold within said at least one membrane analyte assay substrate to distribute said at least one test sample, from said test sample application pad to said plurality of lateral flow and flow thru assays; f) a marker pad positioned next to and distally to each of said sample pads but before said at least one lateral flow assay of each of said membrane platforms, said marker pad allowing for labeling of analytes of said sample; g) at least one analyte assay test zone disposed on each of said lateral flow and flow thru assay: each of said analyte assay test zones being positioned downstream from said marker pad, wherein each of said analyte test zones are positioned on a different in-line horizontal location from any other said analyte test zones of said lateral flow assays of said at least two membrane analyte assay substrates; h) at least one capture reagent disposed at each of the analyte test zones wherein multiple analyte assay test results are simultaneously obtained and in parallel in said diagnostic test device, wherein said lateral flow and flow thru assays on said membrane analyte assay substrates and said analyte assay test zone are positioned to form a readable barcode, and wherein said dispersal of said capture reagent being dispersed in varying band widths to intensity of the color as calibrated by known reagents to allow for a quantitative measurement of the analytes being tested.
