Provided is a blood coagulation analyzer whereby both of an adequate dynamic range and a high sensitivity can be achieved in analyzing blood coagulation, without using any complicated device, by selecting an appropriate detection angle depending on the scattering light intensity of each specimen. The blood coagulation analyzer comprises: a reactor (101) in which a sample and a reagent are mixed together and reacted; a light source (102) for irradiating the reactor (101) with light; multiple detectors (103a, 103b), which are positioned around the reactor (101) at different angles to the light axis of the light from the light source (102), for detecting scattering light generated from the liquid mixture of the sample and the reagent; a memory unit (107) for inputting and memorizing multiple light intensity change data over time obtained from the detectors (103a, 103b); a determination unit (106) for selecting, depending on the amount of light intensity change, light intensity change data to be used in calculating blood coagulation time from among various light intensity change data stored in the memory unit (107); and a calculation unit (108) for calculating the blood coagulation time based on the light intensity change data selected by the determination unit (106). |
