Abstract
Abstract A multiple profile reagent card for simultaneously or sequentially performing multiple analyses of analyte is formed by applying ribbons of reagent impregnated matrix material parallel to each other on a substrate and then removing portions of at least the matrix material to create separate matrices along each ribbon of matrix material. The multiple profile reagent card facilitates automatic processing of immunochemical, diagnostic and/or serological tests.

A multiple profile reagent card comprising multiple reagent impregnated matrices for simultaneously or sequentially performing multiple analyses of analyte wherein the matrices consist of multiple ribbons of reagent impregnated matrix material positioned parallel to each other on a substrate with slots cut completely through said ribbons and said substrate at spaced locations along each ribbon to define matrices along each ribbon, said ribbons being the same or different, said slots extending perpendicular to the length of the reagent impregnated ribbons to substantially prevent runover between adjacent matrices along each ribbon of matrix material, said ribbons of matrix material being applied in a continuous manner to the substrate and then separated by said slots to produce said matrices.
