Abstract:
A test device for analyzing a specific component in a test solution with a reagent by allowing the test solution introduced via a test solution feed opening to react with the reagent maintained in a predetermined position in a capillary tube having the feed opening and an air outlet, said test device comprising:a gas-permeable, liquid-impermeable film blocking an end at the opposite side of the feed opening; and suction generating means for generating suction in the capillary tube via said film, said capillary tube comprising: a first hydrophilic region for transferring the test solution from the test solution feed opening to the reagent; a second hydrophilic region having a predetermined area maintaining the reagent; and a hydrophobic region which separates the first hydrophilic region from the second hydrophilic region and communicates with the air outlet without passing through the first and second hydrophilic regions.
