AUTOMATED ANALYZER

Provided is an automatic analysis device for estimating the cause of variation in the measured value of an accuracy management substance. The present invention is an automatic analysis device for analyzing a specimen, comprising: an acquisition unit for acquiring the amount of variation in the measured value of a precision management substance for precision management; a calculation unit for calculating the predicted amount of variation on the basis of the difference value before and after the batch change of the concentration value of a calibration liquid for calibration; and a calculation unit for calculating the predicted amount of variation on the basis of the result of comparison between the amount of variation and the predicted amount of variation. And an estimation unit that estimates the cause of fluctuation occurring in the measured value of the precision management substance. 本发明提供用于推定精度管理物质的测定值的变动原因的自动分析装置。本发明是用于分析检体的自动分析装置，其特征在于，包括：获取用于精度管理的精度管理物质的测定值的变动量的获取部、基于用于校准的校正液的浓度值的批次变更前后的差分值计算变动预测量的计算部、以
