Abstract

A sample analyzer is disclosed that comprises: an analysis section for analyzing a sample by using a reagent; an information receiver for receiving an input of information regarding the reagent; a determination section for determining, whether or not the reagent satisfies a condition to determine that the reagent is a genuine product, based on the information received by the information receiver; and a controller for controlling an operation of the sample analyzer based on a result of the determination by the determination section.

Claims

1. A sample analyzer comprising:

an analysis section for analyzing a sample by using a reagent;

an information receiver for receiving an input of information regarding the reagent;

a determination section for determining, whether or not the reagent satisfies a condition to determine that the reagent is a genuine product, based on the information received by the information receiver; and

a controller for controlling an operation of the sample analyzer based on a result of the determination by the determination section.

2. The sample analyzer according to claim 1, further comprising:

a display device for displaying an analysis result by the analysis section;

wherein

the controller controls the display device based on the result of determination by the determination section.

3. The sample analyzer according to claim 2, wherein if determined that the reagent does not satisfy the condition by the determination section, the controller controls the display device to display low reliability of the analysis result by the analysis section with the analysis result.

4. The sample analyzer according to claim 2, wherein

the analysis section analyzes a sample containing particles, and obtains numerical data and distribution diagram of the particles contained in the sample;

and

the controller controls the display device to display both the numerical data and the distribution diagram if determined that the reagent satisfies the condition by the determination section, and displays the numerical data without displaying the distribution diagram if determined that the reagent does not satisfy the condition by the determination section.

5. The sample analyzer according to claim 2, wherein

the analysis section analyzes a first analyzing item and a second analyzing item, acquires first numerical data as an analysis result of the first analyzing item, and acquires second numerical data as an analyzing result of the second analyzing item;

and

the controller controls the display device to display both the first numerical data and the second numerical data if determined that the reagent satisfies the condition by the determination section, and displays the first numerical data without displaying the second numerical data if determined that the reagent does not satisfy the condition by the determination section.

6. The sample analyzer according to claim 5, wherein

the first numerical data is basic data used for diagnosis;

and

the second numerical data is auxiliary data used as a reference of diagnosis.

7. The sample analyzer according to claim 2, wherein the controller controls the display device to display a warning that the reliability of the analysis result is low if determined that the reagent does not satisfy the condition by the determination section.

8. The sample analyzer according to claim 7, wherein the controller controls the display device so as to display the warning at least in start up of the sample analyzer.

9. The sample analyzer according to claim 1, wherein the controller prohibits the analyzing operation by the analysis section if determined that the reagent does not satisfy the condition by the determination section.

10. The sample analyzer according to claim 1, wherein the controller automatically validates the analysis result by the analysis section if determined that the reagent satisfies the condition by the determination section, and does not automatically validate the analysis result if determined that the reagent does not satisfy the condition by the determination section.

11. A sample analyzer comprising:

an analysis section for analyzing a sample by using a reagent;

a display device for displaying an analysis result by the analysis section;

an information receiver for receiving an input of information regarding the reagent;

a determination section for determining, whether or not the reagent satisfies a condition to determine that the reagent is a genuine product, based on the information received by the information receiver; and

a display controller for controlling the display device based on a result of the determination by the determination section;

wherein

the display controller controls the display so as to non-display at least one part of the display of the analysis result in the display device if determined that the reagent does not satisfy the condition by the determination section.

12. A sample analyzer comprising:

an analysis section for analyzing a sample by using a reagent;

an information receiver for receiving an input of information regarding the reagent;

a determination section for determining, whether or not the reagent satisfies a condition to determine that the reagent is a genuine product, based on the information received by the information receiver; and

an automatic validation section for automatically validating the analysis result if determined that the reagent satisfies the condition by the determination section, and not automatically validating the analysis result if determined that the reagent does not satisfy the condition by the determination section.

13. The sample analyzer according to claim 12, further comprising a manual validation section for receiving validation of the analysis result by manual operation of the user when the automatic validation section does not automatically validate the analysis result.

14. The sample analyzer according to claim 12, further comprising an automatic output section for automatically outputting the analysis result if determined that the reagent satisfies the condition by the determination section, and not outputting the analysis result if determined that the reagent does not satisfy the condition by the determination section.

15. The sample analyzer according to claim 14, wherein

the automatic output section is set to either a valid setting in which the analysis result is automatically output and an invalid setting in which the analysis result is not automatically output;

and

when the automatic output section is set in the valid setting, the setting of the automatic output section is changed to the invalid setting if determined that the reagent does not satisfy the condition by the determination section.

16. The sample analyzer according to claim 12, wherein

the automatic validation section is set to either a valid setting in which the analysis result is automatically validated and an invalid setting in which the analysis result is not automatically validated;

and

when the automatic validation section is set in the valid setting, the setting of the automatic validation section is changed to the invalid setting if determined that the reagent does not satisfy the condition by the determination section.

17. The sample analyzer according to claim 12, further comprising:

a display device; and

a display controller for controlling the display device to display a warning that the analysis result is not automatically validated if determined that the reagent does not satisfy the condition by the determination section.

18. The sample analyzer according to claim 17, wherein the display controller controls the display device so as to display the warning at least in start up of the sample analyzer.

19. The sample analyzer according to claim 12, wherein

the information receiver receives input of information regarding the reagent when the reagent is changed;

and
