PROBLEM TO BE SOLVED: To realize an autoanalyzer capable of achieving reliable analysis by surely detecting abnormality at the time of dispensation under a dispensation condition where a suction amount is small.SOLUTION: A statistical distance calculation part 206a calculates a characteristic variable to a suction operation in initial dispensation, and calculates statistical distance D from reference data for the characteristic variable extracted from a memory 206b by a reference data selection part 206f. A comparison part 206c compares the statistical distance D with a prescribed threshold stored in the memory 206b, and supplies the result to a determination part 206d. The determination part 206d executes an initial discharge operation when the statistical distance D is lower than the prescribed threshold. A controller determines whether or not it is possible to make a single determination under a dispensing amount condition for dispensation at and after the second time, and when the single determination is determined to be impossible, the controller selects the reference data on the basis of an initial determined amount. The controller determines whether the suction operation at and after the second time is normal or abnormal, on the basis of the selected reference data. |
