NUCLEIC ACID ANALYSIS DEVICE AND DEVICE DIAGNOSIS METHOD

摘要

A nucleic acid analysis device is provided that is capable of quickly detecting device abnormalities, and the like. This device is provided with a temperature control block (1) for holding a tube (10) that includes a sample, a photometer (6), and a device diagnosis unit. The photometer (6) is provided with an LED (11) for irradiating light toward the temperature control block (1) in a state in which the tube (10) is held and a fluorescence detector (20) for receiving light emitted by the sample in response to the irradiation of light from the LED (11). The device diagnosis unit causes the LED (11) to irradiate light toward the temperature control block (1) in a state in which the tube (10) is not held, causes the fluorescence detector (20) to detect the resulting scattered light, and diagnoses the photometer (6) on the basis of the intensity of the scattered light.
