Analyzer, analysis method and computer program product

1. An analyzer apparatus comprising:

a determining unit that determines whether an analysis result of a sample corresponding to a controlled specimen having a known value is normal or not based on an analysis result of the controlled specimen;

a generating unit that generates analysis information in which a determination result by the determining unit is associated with each analysis result of samples; and

an output unit that outputs the analysis information generated by the generating unit, wherein

the determining unit determines the analysis result of the sample is normal when the analysis result of the controlled specimen is a known value and the number of samples in a sample group comprising said analyzed sample is within a predetermined range,

the determining unit determines the analysis result of the sample is in error when the analysis result of the controlled specimen is a known value and the number of samples in said sample group is not within said predetermined range, and

the determining unit determines the analysis result of the sample is abnormal when the analysis result of the controlled specimen is not a known value.

2. The analyzer according to claim 1 , wherein the determining unit determines that the analysis result of the sample within a predetermined range of the sample corresponding to the controlled specimen is normal when the analysis result of the controlled specimen is the known value, and determines that the analysis result of the sample out of the predetermined range is abnormal.

3. The analyzer according to claim 1 , wherein the determining unit determines the analysis result for the sample analyzed after the controlled specimen as the sample corresponding to the controlled specimen.

4. The analyzer according to claim 1 , wherein the determining unit determines the analysis result for the sample analyzed before the controlled specimen as the sample corresponding to the controlled specimen.

5. The analyzer according to claim 1 , wherein the determining unit determines that the analysis result of the sample is normal when first and second controlled specimens each have the known value and the number of samples analyzed between the first and second controlled specimens is within a predetermined range.

6. The analyzer according to claim 2 , wherein the predetermined range is set depending on a content of analysis method for the sample.

7. The analyzer apparatus according to claim 1 , further comprising a storage unit that stores the analysis information.

8. An analysis method, performed by an analyzer apparatus, for analyzing a sample and a controlled specimen having a known value, the analysis method comprising:

determining whether an analysis result of the sample corresponding to the controlled specimen is normal or not based on an analysis result of the controlled specimen;

generating analysis information in which a determination result by the determining is associated with each analysis result of samples, the each analysis result being obtained at the determining; and

outputting the generated analysis information, wherein

the analysis result of the sample is determined normal when the analysis result of the controlled specimen is a known value and the number of samples in a sample group comprising said analyzed sample is within a predetermined range,

the analysis result of the sample is determined in error when the analysis result of the controlled specimen is a known value and the number of samples in said sample group is not within said predetermined range, and

the analysis result of the sample is determined abnormal when the analysis result of the controlled specimen is not a known value.

9. A computer program product having a non-transitory computer readable medium including programmed instructions for analyzing a sample and a controlled specimen having a known value, wherein the instructions, when executed by a computer, cause the computer to perform:

determining whether an analysis result of the sample corresponding to the controlled specimen is normal or not based on an analysis result of the controlled specimen;

generating analysis information in which a determination result at the determining is associated with each analysis result of samples, the each analysis result being obtained at the determining; and

outputting the analysis information, wherein

the analysis result of the sample is determined normal when the analysis result of the controlled specimen is a known value and the number of samples in a sample group comprising said analyzed sample is within a predetermined range,

the analysis result of the sample is determined in error when the analysis result of the controlled specimen is a known value and the number of samples in said sample group is not within said predetermined range, and

the analysis result of the sample is determined abnormal when the analysis result of the controlled specimen is not a known value.
