Abstract
Disclosed is an analysis implement including a support and a reagent layer containing an oxidase applied to the support such that one surface of the reagent layer is exposed to an air atmosphere. A hydrophobic, porous, oxygen permeable layer is positioned between the reagent layer and the support, such that oxygen can permeate to the layer containing oxidase.
