Abstract

In a method of detecting a test substance, a test substance is detected using a sample analysis cartridge supplied with a sample. The sample analysis cartridge includes: a passage part having a gas-phase space; and liquid containers communicating with the passage part through openings. The liquid containers include: a first liquid container containing a first liquid containing magnetic particles; and a second liquid container containing a second liquid containing a labeled substance. The magnetic particles are sequentially transported to the liquid containers through the gas-phase space in the passage part. Thus, the magnetic particles carry a complex of the test substance and the labeled substance. The test substance is detected based on the labeled substance in the complex.
