Abstract
An object of the present invention is to provide a kit, a method, and a reagent which prevent the problem of false positive due to nonspecific adsorption, suppress the increase in noise to be generated, and are capable of achieving high-precision measurement of progesterone in a wide concentration range from a low concentration to a high concentration, in the measurement of progesterone in a biological sample. The present invention provides a progesterone measuring kit including a first particle having a label and modified with a first binding substance, a second particle having no label and modified with a second binding substance, a flow channel, and a substrate, in which the first particle contains a compound represented by Formula (1) and a particle, and an average particle diameter of the first particles is 50 to 250 nm, an average particle diameter of the second particles is 70 to 500 nm, and the average particle diameter of the second particles is larger than the average particle diameter of the first particles. Each symbol in the formula has the meaning described in the present specification.
