The present invention relates to a test piece having a simple structure, by which HDL cholesterol can be measured easily using a small amount of specimen. n A reagent layer ( 2 ) is formed on a support ( 1 ), and an enzyme reagent for measuring cholesterol, a first surfactant that makes a solubility of a high-density lipoprotein (HDL) higher than that of a lipoprotein other than the HDL, and a second surfactant that inhibits the lipoprotein other than the HDL from dissolving are contained in the reagent layer ( 2 ). |
