Abstract: A testing device according to the present invention includes a housing including a skin surface sheet and an upper surface cover. A hollow needle configured to interlock with the upper surface cover and a testing reagent or equipment are accommodated in the housing. Through deformation of the upper surface cover by application of an external force, the hollow needle perforates the skin. A body fluid flows in the space inside of the housing and is brought into contact with the testing reagent or equipment to acquire information on the body fluid. Through recovery of the upper surface cover to an original shape by elimination of the external force, the hollow needle again becomes accommodated in the housing.
