PROBLEM TO BE SOLVED: To improve analyzing performance by keeping conditions of a reagent in a sample storage cabinet excellent by determining whether stirring is necessary for each reagent container and performing control to carry out stirring as necessary.SOLUTION: An autoanalyzer includes: a controller 20 which controls operations of a reagent container transport mechanism 14, a reagent storage cabinet 15, and the like; an arithmetic section which computes a transport amount of a reagent container 16 in the reagent storage cabinet 15 for each of all the reagent containers 16; and a determination section which compares a cumulative transport amount of each reagent container 16 with upper- and lower-limit values of transportation amounts. Each time an analyte is fed to the autoanalyzer and transported to a suction position by rotating the reagent storage cabinet 15, the controller 20 computes and cumulates a transport amount. Further, cumulative transport amounts of all the reagent containers 16 on the reagent storage cabinet 15 are periodically compared with the upper- and lower-limit values. When a cumulative transport amount is equal to or less than the lower-limit value, the reagent container transport mechanism 14 is controlled so as to stir the analyte in the reagent storage container 16. When it is equal to or more than the upper-limit value, over-stirring is determined, and in other states, nothing is carried out. |
