Abstract
A dry test strip for measuring creatinine comprises: a support; a reagent layer that is disposed on the support; a reagent holding layer that is disposed on the reagent layer; and a connection layer that is composed of an adhesive which adhesively bonds the reagent layer to the reagent holding layer and is formed in spot form, wherein the reagent layer contains creatininase and 4-aminoantipyrine; the reagent holding layer contains creatinase, sarcosine oxidase, peroxidase, and N-ethyl-N-(2-hydroxy-3-sulfopropyl)-3,5-dimethoxyaniline; and the connection layer delays arrival of a liquid sample spot-deposited on the reagent holding layer at the reagent layer.
