ABSTRACT:
In an automatic analyzer, waste of specimens and reagents is prevented by having a function for detecting the remaining quantity of the liquids being used such as a reagent, a diluent liquid and a cleaning liquid. The weight data (m) of the reagent container only, and the gross weight data (M) of the reagent container and the reagent in the container are entered in an operation processor of the automatic analyzer, and the reagent remaining quantity (Q)=M-m in the reagent container is determined, while the required reagent quantity (D) necessary for specimen processing of the set specimens is determined, and by comparing the both (Q and D), it is judged whether or not to process the specimens.
