PROBLEM TO BE SOLVED: To enable more accurate examination of coagulability of blood and plasma by means of easier measurement method.SOLUTION: A blood coagulation testing method comprises; a first step S101 for introducing an analyte containing blood components and a coagulation activator that produces fibrin to a flow channel such that the analyte and the coagulation activator are serially arranged in an extending direction of the channel and that adjacent portions are in contact with each other; a second step S102 for stopping the flow of the coagulation activator and the analyte when a contact region between the coagulation activator and the analyte reaches a measurement point set up in the middle of the flow channel to measure condition of fibrin in the contact region; and a third step S103 for determining blood coagulability of the analyte from the measured condition of fibrin.SELECTED DRAWING: Figure 1
