Apparatus for measuring hemostasis includes a container for holding a sample to be tested and a bobber configured to be buoyantly suspended on the sample. A magnet is secured to the bobber. A drive assembly is coupled to the container for driving the container in an oscillating motion. A magnetic field generator is disposed adjacent the container and configured to generate a magnetic field in the vicinity of the magnet. A magnetic field strength detector is disposed adjacent the container, and the magnetic field strength detector is configured to sense changes in the magnetic field as a result of movement of the bobber and magnet responsive to the oscillating motion of the container and clotting of the sample.
