ABSTRACT:
A testing chip that analyzes a specimen includes: a reagent storage section; a mixing and reaction flow channel to perform a series of operations to mix a specimen and aqueous reagent, make the specimen and reagent react with each other, and detect the reaction; and a liquid feed control section provided between an outlet flow channel of the reagent storage section and the inlet of the mixing and reaction flow channel. Herein, aqueous reagent, lipophilic liquid, and aqueous liquid having greater surface tension than that of the aqueous reagent are disposed in the reagent storage section in this order toward the outlet flow channel, the aqueous liquid being stored in contact with the liquid feed control section; and aqueous liquid passes the micro flow path of the liquid feed control section by applying a liquid feed pressure higher than or equal to a predetermined pressure to the reagent storage section.
