Quality control method, quality control system, management apparatus, analyzer, and quality control abnormality determination method

A quality control system comprising:

• a plurality of analyzers installed in a plurality of facilities;
• and
• a management apparatus connected to the plurality of analyzers via a network, wherein
• at least one analyzer of the plurality of analyzers comprising at least one processor configured to:
• measure an artificially generated quality control substance to obtain first quality control information;
• measure a plurality of specimens to obtain a plurality of measurement results;
• obtain second quality control information comprising statistical information obtained by statistical processing by the at least one analyzer of the plurality of measurement results;
• and
• transmit the first quality control information and the second quality control information, via the network, to the management apparatus, and
• wherein the management apparatus is configured to, based on the first quality control information and the second quality control information, output information concerning quality control of the at least one analyzer.

A management apparatus comprising:

• at least one processing device configured to:
• receive first quality control information from a plurality of analyzers located in a plurality of facilities via a network, wherein the first quality control information is obtained by each of the plurality of analyzers measuring at least one artificially generated quality control substance;
• and
• receive second quality control information from the plurality of analyzers via the network, wherein the second quality control information is obtained by each of the plurality of analyzers measuring a plurality of specimens to obtain a plurality of measurement results and obtaining the second quality control information by performing statistical processing of the plurality of measurement results to generate statistical information as the second quality control information;
• and
• outputting information concerning quality control of at least one analyzer of the plurality of analyzers in at least one facility based on the first quality control information and the second quality control information obtained from the at least one analyzer.
