An instrument for sampling a substance to be biologically examined from a specimen, which is characterized by being provided with a sampling part for biologically examined substance composed of a water absorbent material coated with a substantially water-insoluble and water-permeable porous film. By bringing said sampling part of this instrument into contact with the specimen and then with a reagent constituted of a labeled substance specifically bondable to the substance to be examined, the substance to be biologically examined in the specimen can be detected directly, promptly, and easily.
