Patent number: 7575884Abstract: 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. 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).Type: GrantFiled: July 19, 2005Date of Patent: August 18, 2009Assignees: ARKRAY, Inc., Daiichi Pure Chemicals Co., Ltd.Inventors: Hiroshi Tamura, Susumu Nishino, Takehiro Yamaguchi, Koichi Hino
