Patent ID: 8916095

Claim:
An automatic analyzer comprising: a storage unit for storing, on a reagent-by-reagent basis, calibration curve information; and a controller configured to judge, when a reagent set is newly provided for the automatic analyzer, whether or not the calibration curve information of another reagent set for a same analysis item as the newly provided reagent set has already been stored in the storage unit, and whether or not said another reagent set whose calibration curve information has already been stored is effective; wherein the storage unit stores a result of judgment as to whether or not said another reagent set is effective; wherein if the calibration curve information of said another reagent set for the same analysis item as the newly provided reagent set has already been stored in the storage unit, and if said another reagent set is effective, the controller stores in the storage unit the calibration curve information of said another reagent set as the calibration curve information of the newly provided reagent set into the storage unit; wherein if the controller judges that the calibration curve information of said another reagent set for the same analysis item as the newly provided reagent set has been stored in the storage unit but said another reagent set is not effective, the controller creates a calibration curve of the reagent set which is newly provided for the automatic analyzer; wherein said controller stores in the storage unit the calibration curve information of the calibration curve created for the newly provided reagent set, independent of the calibration curve information already stored in the storage unit; and wherein the calibration curve information is a calibration curve factor used to identify a calibration curve.
