Brief Summary:
To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.
