Test piece for measuring protein and method for measuring protein

Abstract

An object of the present invention is to provide a test piece for measuring protein, in which the detection sensitivity during the measurement is improved, and an optical density that can measure the protein in the sample even in a case where a large amount of protein is contained in the sample can be obtained; and a method for measuring protein using the test piece for measuring protein. According to the present invention, there is provided a test piece for measuring protein, including a support and a reagent-holding layer provided on the support, in which the reagent-holding layer contains a coloring agent that changes color in a presence of protein, a molybdate, and a hydroxy acid having a hydroxy group and a carboxy group, and a content of the hydroxy acid is 5 times or more and 40 times or less with respect to the coloring agent that changes color in the presence of protein in terms of molar ratio.
