Reagent preparing device, reagent preparing method and specimen processing system

A reagent preparing method for preparing a reagent to be supplied to a measurement section for measuring a specimen, the method comprising:

• preparing a reagent including a first liquid and a second liquid, different from the first liquid;
• storing the prepared reagent in a reagent storage container connected to the measurement section;
• and
• determining whether or not the reagent stored in the reagent storage container is suppliable to the measurement section based on reagent expiration date information related to an expiration date of the reagent stored in the reagent storage container.

A specimen processing system comprising:

• a measurement section for measuring a specimen using a reagent including a first liquid and a second liquid, different from the first liquid;
• a reagent preparing section for preparing the reagent;
• a reagent storage container, connected to the measurement section, for storing the reagent prepared by the reagent preparing section;
• and
• a controller configured for determining whether or not the reagent stored in the reagent storage container is suppliable to the measurement section based on reagent expiration date information related to an expiration date of the reagent stored in the reagent storage container.
