The present invention provides an automatic analyzer, in which when a specimen that cannot be analyzed due to an abnormality or needs to be remeasured exists, the automatic analyzer can swiftly reload the specimen that cannot be analyzed due to the abnormality or needs to be remeasured without waiting for completion of a measurement of another specimen held by a rack holding the specimen that cannot be analyzed or needs to be remeasured. The automatic analyzer has means for storing information of a rack loaded in the analyzer and specimen information, displaying identification information of the rack loaded in the analyzer to a user, specifying a specimen that needs to be reanalyzed due to an abnormality or needs to be collected for a remeasurement, interrupting analysis of a specimen rack holding the specimen, and collecting the specimen rack. The automatic analyzer can collect and reload the specified specimen.

Automatic analyzer

An automatic analyzer includes a status table storing the status of each analysis module and reagent information identifying each reagent, the supply of which is exhausted, and allowing tracking of the status of each analysis module, etc. The automatic analyzer determines, based on the status table, whether and how it can continue current analysis, and stores the determination results in its instruction information table. The instruction information table stores analysis-unit or -module operating information and information to be supplied to the user or operator. The analysis-unit operating information includes instructions for the analysis modules to initiate an analysis in a normal manner, finish an analysis in a normal manner, omit a pre-analysis operation, omit a post-analysis operation, or stop sampling, etc. Further, the reagent information and the analysis module status are updated each time a reagent container is replaced by the operator.
