Abstract
A testing microchip includes a specimen storage section; a reagent storage section; a reaction section; a testing section for a test of a reaction product obtained from the reaction; a liquid feed control section; and a gas bubble trapping structure. The sections are connected continuously by a series of flow channels. The liquid feed control section stops passing of liquid until a liquid feeding pressure reaches a predetermined pressure, and passes the liquid when the liquid feeding pressure becomes higher than the predetermined pressure; and the gas bubble trapping structure traps a gas bubble in the liquid that flows in the flow channel so that the gas bubble does not flow to the downstream side and only the liquid passes to the downstream side. A testing apparatus that performs testing in the testing section of the testing microchip, wherein the testing microchip is attachably and detachably mounted to the apparatus.
