Abstract
A specimen measurement device which detects a measurement object material according to the present embodiment, includes: a magnetic field applicator configured to apply a magnetic field to a measurement cartridge including a substrate, a first substance fixed on the substrate and specifically reacting with the measurement object material, a magnetic particle, and a substance fixed on the magnetic particle and specifically acting with the measurement object material; a detector configured to detect light passing through the substrate; and a controller configured to control the magnetic field applicator to perform a first operation to apply a first magnetic field in a direction to move the magnetic particle away from the substrate when a specimen solution containing the measurement object material is introduced into the measurement cartridge, and then perform a second operation to apply a second magnetic field in a direction to move the magnetic particle toward the substrate.
