Quality control system, analyzer, and quality control method

A quality control system comprising a plurality of analyzers and a control device connected to the analyzers via a network, the quality control system comprising:

• measurement units for measuring samples, each of the measurement units being provided in each of the analyzers, respectively;
• quality control data transmitters for transmitting, to the control device via the network, quality control data obtained by the measurement units by measuring quality control samples, each of the quality control data transmitters being provided in each of the analyzers, respectively;
• a quality control data receiver for receiving a plurality of quality control data transmitted from each of the quality control data transmitters, the quality control data receiver being provided in the control device;
• a memory for storing the plurality of quality control data received by the quality control data receiver and a calibration uncertainty of each of the analyzers, wherein each calibration uncertainty reflects a first standard deviation of multiple measurement data obtained by each analyzer by measuring a standard substance multiple times, respectively;
• and
• a quality control processor provided in the control device and configured for performing operations comprising:
• when the quality control data receiver has received a quality control data from one analyzer among the plurality of analyzers, implementing a quality control of the one analyzer by calculating at least a second standard deviation of multiple quality control data including the plurality of quality control data of the one analyzer stored in the memory and the received quality control data;
• reading out, from the memory, the calibration uncertainty of the one analyzer;
• obtaining a measurement uncertainty of the one analyzer based on a value expressed below:
• √(UCAL2+UQC2)
• where UCAL represents the calibration uncertaint of the one analyzer, UQC represents the second standard deviation;
• and
• generating a report which includes a result of the quality control of the one analyzer and the measurement uncertainty of the one analyzer.
