Calibration curve generation method, autonomous analysis device, and calibration curve generation program

An automatic clinical analyzer, comprising:

• a light irradiation unit that irradiates, with light, a cell storing a mixed liquid of a specimen in which a component to be measured has an unknown concentration and a reagent;
• a measurement unit that measures light from the mixed liquid;
• and
• an analysis unit that (1) irradiates, with light, a mixed liquid containing one standard solution in which a concentration of the component is not zero and also containing a reagent reacting with the component, thereby measures a time course in which the component to be measured in the one standard solution reacts, (2) extracts pieces of calibration data which are a plurality of pieces of light amount data in a plurality of different times from a fitting line for time course data representing the time course in which the component in the one standard solution reacts, and (3) quantifies a concentration of the specimen by using a calibration curve indicating a relationship between the concentration and the light amount data, and also using light amount data obtained from time course data in the measurement unit, the calibration curve being generated by converting the plurality of different times into a plurality of concentrations of the component.

A calibration curve generation program causing a computer to execute processing of generating a calibration curve in an automatic clinical analyzer that quantifies a concentration of a component to be measured contained in a specimen, the program causing the computer to execute:

• irradiating, with light, a mixed liquid containing one standard solution in which a concentration of the component to be measured is not zero and also containing a reagent reacting with the component to be measured, thereby measuring a time course in which the component to be measured in the one standard solution reacts;
• extracting pieces of calibration data which are a plurality of pieces of light amount data in a plurality of different times from a fitting line for time course data representing the time course in which the component to be measured in the one standard solution reacts;
• and
• generating the calibration curve indicating a relationship between the concentration and the light amount data by converting the plurality of different times into a plurality of concentrations of the component to be measured.
