- each analyzer is determined based on the result of the statistical processing (the magnitude of the absolute value of the difference). For example, as shown in FIG.
- the data value corresponding to the device ID is specified, and after calculating the average value, I data value—average value I is calculated.
- I data value—average value I is calculated.
- the determination result is stored in the inter-device difference data storage unit 65. Then, the determination result may be transmitted to the analyzer 3 so that the determination result is notified to the user of the analyzer 3. Further, for example, for the analysis device 3 determined to have a large difference between the analysis devices, a warning message may be transmitted to the user of the maintenance terminal 9.
- the order processing unit 55 may be formally executed with the maintenance order processing.
- the reagent abnormality predicting unit 63 uses the data stored in the result file storage unit 57 to determine a tendency such as a determination of ineffectiveness or an increase in detection of abnormality for a specific reagent lot, Perform processing such as estimating the occurrence of reagent abnormality. As a result, for example, if the occurrence of a reagent abnormality is estimated with a probability exceeding a predetermined standard in the unusable reagent list in the reagent DB 60, the reagent lot number is registered.
- the device abnormality prediction unit 64 is stored in the result file storage unit 57 and the device DB 59.
- the data is used to determine the tendency of an increase in the number of detected abnormalities for a specific type of analyzer, and to perform a process such as estimating the occurrence of an analyzer error. as a result
- a reagent abnormality prediction unit 63 and an apparatus abnormality prediction unit 64 that use data stored in the result file storage unit 57 are provided so that a specific reagent lot and serial number can be predicted before an abnormality occurs.
- the life of the reagent and the life of the analyzer can be predicted, and the reliability of the entire analysis system can be improved. It also facilitates reagent production management and inventory management. Further, since the user of the analyzer 3 can deal with the abnormality before it occurs, a reduction in the complaint rate is expected.
- an inter-device difference data generation unit 62 that uses the data stored in the result file storage unit 57 is provided, and the difference data between the analysis devices can be collected. Measures to reduce the difference between analyzers (including setting correction coefficients) can be made at any time, and the accuracy of data can be improved.

- production management and inventory management can be performed using this data.
- analyzer Information useful for reagent manufacturers and analyzer manufacturers such as extracting improvements It ’s like being able to get
- the host computer 5 can realize the functions described above with a plurality of computers instead of a single computer. Further, the functional sharing between the analyzer 3 and the host computer 5 can be changed to some extent. For example, the host computer 5 may make all judgments regarding the availability of reagents before analysis, or the latest necessary data may be sent to the analyzer 3 and all judged by the analyzer 3. It is okay to send the results to the host computer 5. Similarly, the determination of the analysis result after the analysis can be performed entirely by the host computer 5 V, and the necessary data is transmitted to the analysis device 3 and executed by the analysis device 3 for analysis. The result may be sent to the host computer 5.
