Measurement method and measurement device

A measurement method for measuring a detection material contained in a sample by using a cartridge comprising:

• chambers each capable of housing at least one of the detection material and a reagent;
• and a path through which the detection material is transferred between a first chamber and a second chamber of the chambers, the method comprising:
• positioning the first chamber to an image capturing range by rotating the cartridge about a rotational shaft;
• capturing, by an image capturing unit an image of the first chamber that is positioned in the image capturing range by rotating the cartridge;
• positioning the second chamber to the image capturing range by rotating the cartridge about the rotational shaft;
• capturing, by the image capturing unit, an image of the second chamber that is positioned in the image capturing range by rotating the cartridge;
• and
• measuring, by a measurement unit which is different from the image capturing unit, the detection material in at least one of the chambers, which is positioned at a measurement position by rotating the cartridge;
• and
• checking whether a measurement processing is appropriately performed or whether anomaly occurs in the measurement processing based on the captured images of the first chamber and the second chamber.
