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.
