An automatic analyzer includes a control unit 7d that, when an accuracy control sample is put in after input of a standard sample, requests measurement of the input accuracy control sample on the same measurement item as a requested measurement item for the standard sample; and a selection screen 201 or 501 that enables selection of measurement timing of the accuracy control sample on the same item as the requested measurement item for the standard sample. The control unit 7d starts measurement of the accuracy control sample when the timing selected on the selection screen 201 or 501 is reached. This reduces consumption of the standard sample and reagent as compared with before and provides an automatic analyzer that can improve analysis throughput.

Provided is an automatic analysis device in which a step for checking the progress of deterioration of a reagent can be automated and the expiration date of the reagent can be managed. Properties in absorption spectroscopic analysis pertaining to a standard liquid during implementation of calibration are used to calibrate the automatic analysis device so as to generate a standard curve N times for each lot. A series of action are repeated, with successive results in the implementation of calibration being updated while N is increased by 1 for each instance, until a first lot is completed. The final results are displayed in a dedicated screen image. This makes it possible to preliminarily ascertain the deterioration of the reagent, therefore making it possible to preemptively prevent inferiority in terms of repeatability and linearity, as well as to contribute to freedom from complex operations, reduction of cost, improvement in quality of data, and prevention of medical malpractice caused by a delay in reporting.
