Abstract: A test device, test system, and control method of the test device, which defines a light irradiating area in a reactor to prevent a decrease in magnitude of a detected signal that may result due to scattering of light that has penetrated other area of the reactor than an area containing an object for detection and improve a dynamic range. A test device may include a light source configured to irradiate light; a reactor configured to include at least one first area to contain an object for detection; and a photo detector configured to receive light that has been irradiated from the light source and has passed the reactor that contains the object for detection, wherein the light source is configured to limitedly irradiate the light to the first area of the reactor.
