Abstract of the Disclosure The present invention concerns a multilayer element for the analysis of liquids which comprises, in the form of an intergral arrangement, (1) a reagent layer including a composition comprising material that is reactive or otherwise interactive in the presence of a substance to be analyzed (analyte) to provide a diffusible, detectable species, and (2) a registration layer that is permeable to the detectable species and within which such species, e.g., a dye, can be detected. Also within the element, between the reagent layer and the registration layer, there is a radiation-blocking layer, such as an opaque reflecting layer, to enchance detection of the diffusible species within the registration layer. In operation, a detectable species formed within the reagent layer will permeate the registration layer whereby an analytical result produced within the element can be detected.
