Abstract
A diagnostic test strip for the detection of a analyte in a test fluid. The test strip has a reagent layer on a support layer. The reagent layer contains an analyte detection system in a non-particulate dialyzed latex polymer.
Claims8
A diagnostic test strip for the detection of a predetermined substance in a fluid wherein the strip comprises a support having thereon a reagent layer wherein the reagent layer contains a non-particulate dialyzed latex polymer and dispersed therein a reagent detection system consisting essentially of one or more reagent compositions which react with the substance to provide a detectable change, wherein the dialyzed latex polymer constitutes at least about 60% by weight of the dry reagent layer.
A diagnostic test strip comprising a transparent support having thereon a reagent layer comprising dialyzed non-particulate carboxylated vinylacetate/ethylene copolymer and dispersed therein a reagent detection system consisting essentially of glucose oxidase, peroxidase, and a color indicator that changes color when exposed to glucose, wherein the dialyzed latex copolymer constitutes at least about 60% by weight of the dry reagent layer.
