Abstract

An analyzer includes a management unit that manages initiation timings of a calibration analysis process, in which a calibrator is analyzed, and a blank analysis process, in which a blank sample is used, independently for each of the analytical items. The management unit performs at least the blank analysis process before an expiration date for managing accuracy of a result of the blank analysis and when a reagent is supplied, and the management unit performs the calibration analysis process before an expiration date for managing accuracy of a result of the calibration analysis and when the reagent is supplied.

Claims

1. An analyzer comprising:

a management unit that manages initiation timings of a calibration analysis process, in which a calibrator is analyzed, and a blank analysis process, in which a blank sample is used, independently for each of the analytical items, wherein

the management unit performs at least the blank analysis process before an expiration date for managing accuracy of a result of the blank analysis and when a reagent is supplied, and

the management unit performs the calibration analysis process before an expiration date for managing accuracy of a result of the calibration analysis and when the reagent is supplied.

2. The analyzer according to claim 1, wherein the management unit performs, when the reagent is supplied, the calibration analysis process corresponding to lot information or bottle information of the supplied reagent, and the blank analysis process corresponding to the lot information or the bottle information of the supplied reagent.

3. The analyzer according to claim 2, wherein when the management unit performs the calibration analysis process corresponding to the lot information of the reagent to manage the analysis accuracy of the analyzer, the management unit performs the calibration analysis process when the lot information of the supplied reagent is different from lot information of the reagent used for the calibration analysis process that has already been performed, and the management unit uses a result of the calibration analysis corresponding to the reagent used for the calibration analysis process that has already been performed when the lot information of the supplied reagent is the same as the lot information of the reagent used for the calibration analysis process that has already been performed.

4. The analyzer according to claim 2, wherein when the management unit performs the blank analysis process corresponding to the lot information of the reagent to manage the analysis accuracy of the analyzer, the management unit performs the blank analysis process when the lot information of the supplied reagent is different from lot information of the reagent used for the blank analysis process that has already been performed, and the management unit uses a result of the blank analysis corresponding to the reagent used for the blank analysis process that has already been performed when the lot information of the supplied reagent is the same as the lot information of the reagent used for the blank analysis process that has already been performed.

5. The analyzer according to claim 1, further comprising:

a configuration unit that configures the initiation timings of the calibration analysis process and the blank analysis process for each of the analytical items; and

a storage unit that stores the initiation timings of the calibration analysis process and the blank analysis process for each of the analytical items, wherein

the management unit performs the calibration analysis process and the blank analysis process with reference to each of the initiation timings stored in the storage unit.

6. The analyzer according to claim 1, wherein the management unit obtains for each of the analytical items the expiration date of the result of the calibration analysis, based on a date of the calibration analysis process and a validity duration for managing accuracy of the result of the calibration analysis, and the expiration date of the result of the blank analysis, based on a date of the blank analysis process and a validity duration for managing accuracy of the result of the blank analysis.

7. The analyzer according to claim 6, further comprising an output unit that outputs the expiration date of the result of the calibration analysis and the expiration date of the result of the blank analysis, which are obtained by the management unit for each of the analytical items.

8. The analyzer according to claim 1, wherein the management unit performs the calibration analysis process when the management unit determines that the expiration date of the result of the calibration analysis is to be expired within a first predetermined period of time.

9. The analyzer according to claim 1, wherein the management unit performs the calibration analysis process along with the blank analysis process when the management unit determines that the expiration date of the result of the blank analysis is to be expired in a second predetermined period of time and further the expiration date of the result of the calibration analysis is to be expired within a third predetermined period of time.

10. The analyzer according to claim 8, wherein the first predetermined period of time is set based on a time period that is required for the calibration analysis process.

11. The analyzer according to claim 9, wherein the second predetermined period of time is set based on a time period that is required for the blank analysis process, and

the third predetermined period of time is set based on a time period that is required for the calibration analysis process and the time period that is required for the blank analysis process.
