The present invention provides an automatic blood-sampling tube preparation system which can reduce the reading mistake of the information of the RFID tags by selectively taking out a blood-sampling tube required to an examination of a patient according to a doctor's instruction information from the blood-sampling tube containing section, writing the patient examination information on a RFID tag of the taken out tube on the basis of the instruction information, reading simultaneously all patient examination information from all RFID tags contained in the prepared container for every patient, and comparing the information read from the RFID tags with the instruction information to ensure accuracy.
