What this Trial Is About
Researchers are conducting a natural history study to collect blood samples from healthy adults to support research on diseases involving blood, blood vessels, and the immune system. The study aims to establish normal physiological parameters and validate technical tests for vascular inflammation and thrombosis. This research will help improve understanding and testing methods for vascular and immunologic diseases. Participants will provide blood samples during visits to the NIH Clinical Center, where about 10 tablespoons of blood will be drawn from a vein. Blood tests may include complete blood count and blood typing, and the samples will be used for genetic studies and other research assays. Some participants may return for repeat visits over a period of up to 10 years to provide additional samples and updated medical history. During the study, participants will have their medical history reviewed remotely via telehealth or telephone and in person during visits. The research team will monitor the collected blood samples to optimize assays and study vascular biomarkers. Participants will receive $50 for each blood collection visit. The study is designed to follow Good Clinical Practices and does not have a specific outcome measure but supports ongoing and future research.
