An object of the present invention is to rapidly measure an index of a coagulation active factor. A coagulation activity measurement apparatus includes a surface plasmon resonance measurement apparatus that measures a refractive index on a surface of a flow path of a measurement chip 100 including a flow path through which a solution flows. The surface plasmon resonance measuring apparatus includes a prism 1, a light source 2, a polarizing plate 3, a condenser lens 4, a CCD camera 5, and a data processing device 6. Further, in the data processing device 6, after the buffer solution is filled in the flow channel of the measurement chip 100, a plasma sample in which an activator that activates blood coagulation and plasma are mixed is put into the flow channel. The flow rate calculated by the flow rate calculation unit based on the known relationship between the flow rate of the plasma and the index of the coagulation activity factor from the change in refractive index A coagulation activity factor index calculating means for calculating an index of the coagulation activity factor from [Selection] Figure 4 |
