1. An automatic analysis device, comprising:

  • a sample vessel placing section in which a first sample vessel containing a biological sample to be analyzed and a second sample vessel containing a blood clot time reference sample that has a known blood clot time are placed;

    a reagent vessel placing section in which a plurality of reagent vessels each containing a reagent and each having a barcode attached thereto are placed;

    a reaction vessel;

    a sample dispensing mechanism which dispenses the biological sample or the blood clot time reference sample into the reaction vessel;

    a reagent dispensing mechanism which dispenses the reagent into the reaction vessel from the reagent vessel;

    a detector which detects a signal value that changes over time in accordance with a mixing reaction of the reagent and the biological sample or the blood clot time reference sample;

    a barcode reader;

    a control section programmed to;

    control the barcode reader to read information from a barcode on a first reagent vessel of the plurality of reagent vessels,obtain an expected blood clot time based on the information read from the barcode,control the detector to detect first signal values from a mixture of the blood clot time reference sample and the reagent and generate a first reaction curve based on the first signal values,determine a signal reference value based on the first reaction curve and the expected blood clot time,store the signal reference value in association with identification information of the reagent,control the detector to detect second signal values from a mixture of the biological sample and the reagent and generate a second reaction curve based on the second signal values,determine whether the expected value of blood clotting time is in a predetermined range,upon determining the blood clotting time is not in the range, issue an alarm on a display, anddetermine the blood clotting time of the biological sample based on the signal reference value and the second reaction curve of the biological sample.
