1. A biochemical analysis method of performing a biochemical analysis of a specimen by reacting the specimen and a reagent in a reaction container, the method comprising, in an accommodation container accommodating an accommodation object which is the specimen or the reagent and that includes a cover member:
providing a piercer for piercing the cover member, where the piercer extends in a direction and has an opening therethrough;
providing a nozzle for suctioning the accommodation object, where the nozzle is sized to be able to pass through the opening of the piercer;
driving the piercer towards the cover member to attempt to pierce the cover member using the piercer;
driving the nozzle in the direction of extension of the piercer to attempt to pass the nozzle through the opening of the piercer and suction the accommodation object accommodated by the accommodation container using the nozzle;
providing an error notification upon detection of contact of a nozzle with a droplet of the accommodation object in the piercer; and
providing an error notification upon detection of a collision of the nozzle with the cover member.
