Brief Summary:
The objective of this study will be to assess the coagulation system in-vitro in a variety of bleeding and clotting disorders using the ROTEG analyzer and the thrombin generation assay.

Condition or disease
Blood Coagulation Disorders, Inherited Thrombotic Disorder

Detailed Description:
This is an exploratory study involving blood coagulation assays in a select group of individuals. The ROTEG is a newly developed coagulation analyzer which allows the continuous assessment of whole blood coagulation from the formation of the first fibrin fibers and activated platelets, to the formation of a three-dimensional whole blood clot until the eventual dissolution of the clot. This device will not be used as a diagnostic or procedure tool. No recommendations regarding interpretation of the results or implications for future treatment will be provided.
