Abstract
An assay device includes: a liquid sample zone; a reagent zone downstream and in fluid communication with the sample zone that includes a reagent cell having a line of symmetry in the direction of fluid flow; a reagent material in the reagent cell, wherein the reagent material includes a first reagent material located at the axis of symmetry and is left-right symmetric, and a second and third reagent material having a substantially identical shape and volume and located in mirror locations from the line of symmetry; a detection zone in fluid communication with the reagent zone; and a wicking zone in fluid communication with the detection zone having a capacity to receive liquid sample flowing from the detection zone. The sample addition zone, the detection zone and the wicking zone define a fluid flow path.
