Abstract: To provide a test substance measurement method and a test substance measurement kit adapted to improve the accuracy of the measurement of a test substance. A test substance measurement kit includes: fluorescent particles which are modified with a first binding substance having specific bindability to a test substance; non-fluorescent particles which are modified with a second binding substance having no specific bindability to the test substance; and a substrate on which a first metal film to which a third binding substance having specific bindability to the test substance is fixed, and a second metal film to which a fourth binding substance having no bindability to the test substance, but having bindability to the first binding substance is fixed, and which has a smaller thickness than the first metal film are formed.

Abstract: An object of the present invention is to provide a reagent kit, a measurement kit, and a measurement method for measuring serum amyloid A, which enable measurement having a high correlation of an increase in signal with respect to the concentration of serum amyloid A. According to the present invention, provided is a reagent kit for measuring serum amyloid A, including first particles having a label and modified with a first binding substance having a property of specifically binding to serum amyloid A, and at least one nonionic surfactant having an HLB value of 17 to 20, which is defined by (inorganicity value/organicity value)×10 and a molecular weight of 1000 or less.
