Abstract
Disclosed is a detection apparatus that transfers magnetic particles through a plurality of chambers in a cartridge which includes the plurality of chambers and a channel connecting between the plurality of chambers, and that causes the magnetic particles to carry a complex of a test substance and a labelling substance, to detect the test substance on the basis of the labelling substance in the complex. The detection apparatus includes: a rotation mechanism configured to rotate the cartridge about a rotation shaft; a magnet configured to collect the magnetic particles in the chambers; a movement mechanism configured to move the magnet in a direction different from a circumferential direction of a circle in which the rotation shaft is centered; a detector configured to detect the test substance; and a controller programmed to control the rotation mechanism and the movement mechanism so as to transfer the magnetic particles from one of the chambers to another one of the chambers.
