Abstract: A blood analyzing method includes optically measuring a first calibration sample prepared from a fibrin/fibrinogen degradation product (FDP) measurement reagent and a first calibrator containing D-dimer (DD) and having a first value relating to the ratio of the content of FDP to the content of DD, acquiring first calculation data based on temporal change of optical information of the first calibration measurement sample, performing optical measurement of a second calibration measurement sample prepared from FDP measurement reagent and a second calibrator containing DD and having a second value that is different from the first value, acquiring second calculated data based on a temporal change in optical information of the second calibration measurement sample, and acquiring calibration curve information indicating the relationship between the calculation data and the value relating to the amount of DD.

Abstract: Disclosed is a blood sample analyzing method including preparing a measurement specimen by mixing a blood sample with a measuring reagent of fibrin and a fibrinogen degradation product (FDP); acquiring, based on a time-dependent change in optical information obtained by optically measuring the measurement specimen, first information indicating an FDP concentration and second information indicating a curving degree of a time course curve showing the time-dependent change of the optical information; and determining an enhanced fibrinolytic state of the blood sample or acquiring a value related to a D dimer of the blood sample based on the first information and the second information.
