PROBLEM TO BE SOLVED: To enable appropriate management of reagents. SOLUTION: In an analysis system having an analysis apparatus using a reagent container having a memory to store reagent information concerning a reagent in the container and a remote computer, the following steps are executed: reading out the reagent information from the memory of the reagent container; determining, based on the reagent information, whether or not the reagent in the reagent container is usable; writing data representing the reagent is unusable into the memory of the reagent container when the reagent in the reagent container is determined to be unusable; and registering the data representing the reagent is unusable in a reagent database managed by the remote computer corresponding to reagent container ID when the reagent in the reagent container is determined to be unusable. Thus, it is possible to manage reagents so as not to use a reagent, which must not be used, for analysis by automatically identifying it. In addition, it is possible to use the data for improvement of the efficiency in business operations such as the automatic order of reagents, stock management in a manufacturer and the like.
