1. A method for measuring hemostasis comprising:
- providing a blood sample exciting the blood sample to a resonant state by displacing the blood sample to create movement in the blood sample;
observing the movement in the blood sample;
periodically determining a resonant frequency of the blood sample to provide a plurality of resonant frequencies of the blood sample and deriving the hemostasis characteristics of the blood sample from the plurality of resonant frequencies of the blood sample.

Abstract
A method and device for blood hemostasis analysis is disclosed. A blood sample is displaced to reach a resonant state. The resonant frequency of the blood sample is determined before, during and after a hemostasis process. The changes in the resonant frequency of the blood sample are indicative of the hemostasis characteristics of the blood sample.

7. A method for measuring hemostasis comprising:
- placing a blood sample in a container having a portion transparent to an emission from a sensor;
displacing the container with an shaker to cause movement in he blood sample;
measuring the movement in the blood sample with a sensor receiving the emission indicative of the movement of the blood sample, wherein the emission contact at least a portion of the blood sample before being received by the sensor;
periodically determining a resonant frequency of the blood sample from the movement of the blood sample to provide a plurality of resonant frequencies of the blood sample; and
