ABSTRACT:
A test device1for analyzing a specific component in a test solution with a reagent by allowing the solution introduced via a feed opening4to react with the reagent maintained in a predetermined position in a capillary tube3having the opening4and an air outlet5. The tube is provided with two hydrophilic regions31, 33and a hydrophobic region32. The region31transfers the solution from the opening4to the reagent. The region33is delimited to a predetermined area maintaining the reagent. The region32separates the region31from the region33. The reagent and the solution are applied in predetermined amounts to the region33. A measuring device need not previously measure the solution. The device is useful as an analytical device for rapid and easy analysis, and can be produced in a less number of steps because the reagent can be fixed by merely applying it onto a predetermined position.
