Automatic analyzer

An automatic analyzer can be promptly repaired when the abnormal state occurs, reducing the non-operating time, automatically performing reinspection required for the analysis. The reliability of analysis results can be obtained efficiently. An automatic analyzer includes a storage unit for storing information about the operation of equipments of the automatic analyzer, information about usage histories of expendable supplies provided for the analysis, and an analysis-ID control unit giving an ID to the analysis, the analysis ID being used as information for identifying the analysis to derive a calibration curve. Data stored in the storage unit is organized along the same time axis both in the order of samples subjected to the analysis and inspection, and in the order of analysis items, so that the data is output in a total data display area. The data is organized from the viewpoint of an analysis process of an analysis item of each sample. By use of information used to identify an influence range based on a kind of an abnormal state, which is stored beforehand, a judgment is made as to whether or not it is necessary to perform reinspection.
