Summary:1 34 6 32357 23 146 4 The present invention provides a novel test piece for creatinine measurement. The test piece includes a compound expressed by the following formula (1), a metal that forms a colored complex with the compound, and a buffer agent in a porous material. The amount of creatinine is determined by optically measuring a colored complex of the compound and the metal and evaluating the degree of inhibition of the colored complex formation by creatinine. In the formula (1), Rrepresents H, SOX, or COOX. Rand Rrepresent OH, SOX, or COOX and may be either the same or different. R, R, R, and Rrepresent H, OH, Cl, Br, I, NO, NO, or CHand may be either the same or different. Xs in the R, R, and Rrepresent H, Na, K, or NHand may be either the same or different.
