Abstract: A blood coagulation system analysis apparatus includes: an estimating unit that estimates a characteristic regarding an inhibitor of a blood coagulation factor on a basis of a comparison result between a first result regarding a blood coagulation inhibition ability of the inhibitor of the blood coagulation factor and a second result regarding the blood coagulation inhibition ability, the first result being obtained on a basis of at least one electrical characteristic of a first blood sample to which the blood coagulation factor is added, and the second result being obtained on a basis of at least one electrical characteristic of a second blood sample, wherein the second blood sample contains either a concentration of the blood coagulation factor which is different from the concentration of the blood coagulation factor in the first blood sample or does not contain any blood coagulation factor.

Abstract: To provide a blood coagulation system analysis device capable of easily and rapidly evaluating a human tissue factor pathway inhibitor. A blood coagulation system analysis device provided with a pair of electrodes, an application unit that applies an alternating voltage to the pair of electrodes at a predetermined time interval, a measurement unit that measures complex permittivity of a blood sample arranged between the pair of electrodes, and an analysis unit that evaluates a human tissue factor pathway inhibitor (TFPI) on the basis of the complex permittivity at a specific frequency in a predetermined period measured at the time interval after anticoagulant action acting on the blood sample is released.

Abstract: Provided is a technology that enables evaluation of a characteristic of an inhibitor of a blood coagulation factor. A blood coagulation system analysis apparatus includes: an estimating unit that estimates a characteristic regarding an inhibitor of a blood coagulation factor on a basis of a comparison result between a first result regarding a blood coagulation inhibition ability of the inhibitor of the blood coagulation factor and a second result regarding the blood coagulation inhibition ability, the first result being obtained on a basis of at least one electrical characteristic of blood to which the blood coagulation factor is added, and the second result being obtained on a basis of at least one electrical characteristic of the blood to which the blood coagulation factor is added so that a concentration of the blood coagulation factor is different from a concentration of the blood coagulation factor in the blood to which the blood coagulation factor is added or the blood coagulation factor is not added.
