ABSTRACT OF THE DISCLOSURE This invention provides a simplified measuring apparatus for use in the qualitative or quantitative measurement of substances to be assayed, such as proteins, antibodies and the like, in a small amount of test samples by a simple and easy operation without requiring a B/F separation step, as well as a process for the measurement by the measuring apparatus. More particularly, it provides a simplified measuring apparatus for use in the detection of the presence and quantity of substances to be assayed in test samples, which comprises: (a) a liquid permeable porous reaction membrane whose surface having at least one reaction area to which an affinity substance capable of directly or indirectly capturing a substance to be assayed or a soluble agent is immobilized; (b) a porous body arranged on the upper part of the porous reaction membrane, to which a soluble agent capable of being solubilized by the addition of a test sample is adhered in a releasable manner; (c) an absorption member arranged on the lower part of the porous reaction membrane, which contacts with a periphery, excluding the reaction area, of the porous reaction membrane via a liquid non-permeable sheet; (d) a liquid non-permeable transparent cover arranged on the lower part of the absorption member; and (e) a liquid non-permeable case which encloses the foregoing members (a) to (d), having an opening for use in test sample introduction on its top surface and another opening for judgement use on its under surface.
