  • Patent number: 12203951
    Abstract: Since the measurement start timings for a plurality of specimens in different test fields deviate from one another, the measurement results are not coordinated, leading to a delay in reporting. When determining an order for measuring a newly recognized specimen using an automated analysis device capable of performing measurements in a plurality of test fields, the measurement order for specimens waiting to be measured is changed to minimize the time difference between measurement result output timings for a plurality of specimens for the same patient, with reference to specimen information such as urgent test information, a measurement completion time, and an earliest measurement completion time for other specimens, relating to the patient's other specimens having the same patient number in the specimen information.
