Automated analyzer

The present invention provides an automated analyzer not requiring the operator to set a new quality control material and to request measurement during the analysis of a sample, capable of continually verifying the appropriateness of the results of measurement of a standard sample by successively carrying out the measurement of a standard sample and that of a quality control material for the same reagent, and capable of guaranteeing the reliability of results of analysis with high reliability A set standard sample is identified, and a quality control material relevant to a reagent requested by the standard sample and stored in a buffer is fed automatically to an analyzer module. The measurement of the quality control material is performed immediately after the measurement of the standard sample for the reagent. A warning signal is generated to prompt the operator to replenish the quality control material when it is decided from the amount of the residual quality control material stored in the buffer that the quality control material is insufficient.
