Test container and nucleic acid test method

A test container including an inlet into which a sample solution is to be put, a first chamber in which the sample solution to be fed from the inlet is stored, and a second chamber in which the sample solution to be fed from the first chamber is stored, the test container being attached to a centrifuge and the sample solution being transferred from the first chamber to the second chamber in order by a centrifugal force caused by a rotation of the centrifuge, the test container comprising:

• an attachable and detachable lid part that covers the inlet;
• a liquid reservoir portion that stores the sample solution put in from the inlet in front of the first chamber;
• and
• a valve that is disposed between the first chamber and the second chamber, includes a liquid storage portion temporarily storing the sample solution to be fed from the first chamber to the second chamber, and is capable of switching between a first state where the first chamber and the liquid storage portion communicate with each other and the second chamber and the liquid storage portion do not communicate with each other, a second state where the second chamber and the liquid storage portion communicate with each other and the first chamber and the liquid storage portion do not communicate with each other, and a third state where both of the first chamber and the second chamber do not communicate with the liquid storage portion,
• wherein a volume of the liquid reservoir portion is larger than a volume of the first chamber, the first chamber and the liquid reservoir portion are connected to each other only by a liquid flow channel through which the sample solution is fed, the first chamber and the second chamber are connected to each other only by a liquid flow channel through which the sample solution is fed, and a vent flow channel through which gas is released from the first chamber is not provided.
