  The storage unit 78, the communication unit 72, the HbA1c measurement unit 71 (the second HbA1c measurement unit), the bar code reader 73, the transport unit 74, the input unit 75, and the display unit 76 of the second HbA1c measurement device 70 are the first It is the same as each means described in the HbA1c measurement apparatus 30. Although the storage unit 78 of the second HbA1c measurement device 70 stores the measurement results of the previous HbA1c in the same manner as the storage unit 38 of the first HbA1c measurement device 30, the storage unit 78 of the first HbA1c measurement device 30 By transmitting measurement data to the storage unit 38 and storing it, the storage unit 78 of the second HbA1c measurement apparatus 70 may not store the past measurement results.

  Based on the flowchart shown in FIG. 4, the outline | summary of the control process of the reexamination which the measurement system 10 which concerns on this Embodiment performs is demonstrated. In addition, the said process is a process regarding the biological sample of the same patient.

  First, in step 110, the first HbA1c measurement apparatus 30 measures HbA1c in the blood of a patient among the biological samples stored in the sample container 140 of the sample rack 150. Thereafter, the sample rack 150 is transported to the glucose measuring device 50 by the transporting means 34, and glucose in the blood of the patient is measured by the glucose measuring device 50. Then, the process proceeds to the next step 111. The measurement order of HbA1c and glucose may be reversed.

  In step 111, it is determined whether the measurement value of the glucose measurement means of the glucose measurement device 50 of a certain patient is equal to or greater than a predetermined threshold. If it is determined that the threshold value is equal to or more than the predetermined threshold value, the process proceeds to the next step 112, and if it is determined that the threshold value is not equal to or more than the predetermined threshold value, the process ends.

In step 112, the instruction means 120 conveys the sample container 140 to the second HbA1c measurement apparatus 70 and instructs the re-examination of the HbA1c. Then, the process proceeds to the next step 113.
In step 113, measurement (re-examination) of HbA1c is performed by the second HbA1c measurement apparatus 70. Then, the process ends.
If it is determined in step 111 that the value is not equal to or greater than the predetermined threshold value, the sample container 140 of the patient is transported to the second HbA1c measurement apparatus 70, but only the transport is performed, and the measurement of HbA1c is not performed. Of course, when it is determined that the value is not the predetermined threshold or more, the second HbA1c measuring device 70 may be prevented from being transported, and may be taken out on the left side in front of the glucose measuring device 50.

  The above-described processing procedure is processing for the same patient, and even when a plurality of sample containers 140 of different patients are included in the sample rack 150, the processing procedure for the same patient is the above-described processing procedure. It is a thing.

  In the case where a plurality of sample containers 140 of different patients are included in the sample rack 150, when the sample rack 150 is transported to each measurement position in each measurement device, all the sample containers 140 at that measurement position. The sampling and measurement are performed on the biological sample of As a result, if one of the sample containers 140 is retested and the other sample containers 140 are not retested, the sample rack 150 is transported along the transport route in the case of retesting. However, for each sample container 140, one to be re-inspected by the barcode reader 73 is distinguished from one not to be re-inspected, and only the sample container 140 to be re-inspected is to be subjected to the re-examination of HbA1c.

  In the present embodiment, by having the above-described configuration, the following actions and effects are achieved.

  In the present embodiment, when the measurement value of the glucose measurement means 51 of a certain patient is equal to or greater than the predetermined threshold value, the sample container 140 is transported to the second HbA1c measurement apparatus 70 by the transport means 94 (34, 54, 74). Then, the instruction means 120 instructs the second HbA1c measurement device 70 to re-examine the HbA1c of the patient's biological sample. Then, based on the instruction, the second HbA1c measurement device 70 executes the re-examination of the HbA1c.

  For example, when two HbA1c measuring devices are operated individually, and the present embodiment is compared with what is judged by a doctor or a person in charge of inspection each time based on the measurement result each time, the present embodiment Then, the two HbA1c measuring devices can be linked without intervention of the judgment of a doctor or a person in charge of inspection every time, and it becomes possible to uniformly process the re-examination of HbA1c in a short time.

  That is, according to the present embodiment, when the measurement value of the glucose measurement means 51 of a certain patient is equal to or more than the predetermined threshold value, the sample container 140 is transported to the second HbA1c measurement device 70 using the transport means 94. The instruction means 120 instructs the second HbA1c measurement device 70 to re-examine the HbA1c of the patient's biological sample. Since the doctor or the person in charge of inspection does not judge the measurement result each time, it becomes possible to process uniformly and accurately in large quantities without being affected by human-induced judgment errors.

  As described above, HbA1c measurement work can be efficiently executed by enabling execution of a series of processes from transport of a biological sample of the same patient to re-examination instructions and execution based on measurement results. It is possible to perform the judgment of the re-examination of HbA1c easily and reliably.

In the present embodiment, communication means 92 (32, 52, 72) capable of transmitting and receiving measurement results between first HbA1c measuring device 30 and second HbA1c measuring device 70 are provided, and storage means 38 and instruction means 120. Is provided in the first HbA1c measuring device 30, so that a plurality of measuring devices can be operated and managed as one system without separately providing a dedicated host computer 20 for managing them. .
