Are you an adult with sickle cell disease or would like to help research? Some people who have sickle cell disease are at greater risk for developing abnormal blood clots (venous thromboembolism). This could be a blood clot in the leg (called deep vein thrombosis) or a clot that can break off and travel to the lung (called a pulmonary embolism). This study will look at the blood of people who have sickle cell disease and venous thromboembolism, as well as healthy volunteers, to help researchers develop better treatments to prevent blood clots. Participants in this study must be between 18 and 80 years old and be either a healthy volunteer or have sickle cell disease or trait. This study is located in Bethesda, Maryland.

Are you an adult willing to give blood samples? This study investigates ways to prevent blood clotting in people with sickle cell disease. In this population, blood clotting is the most common cause of vascular death after heart attack and stroke. Scientists are studying the blood of people with sickle cell disease and comparing it with the blood of people without sickle cell disease over 2 years. To participate in this study, you must be between the ages of 18 and 80 years old and willing to participate for up to 2 years. This study takes place in Bethesda, Maryland.
