An apparatus and a method for determining the coagulation time of blood are shown. Surface waves are injected into a blood sample (30) therein, which blood sample contains fluorescent microspheres (32). The fluorescence of the microspheres is excited, and the movements of the microspheres are optically monitored. The time of coagulation can be determined using the deceleration or the standstill of the movement of the microspheres. |
