Bethesda, MarylandAges 18–65 - NCT00001620Enrolling by invitation
NIH screening to see which blood studies fit you
This study is a general screening step at the NIH Clinical Center to check whether you might qualify for other NHLBI research protocols. It helps match you (or a donor/healthy volunteer) to the right study and confirms you can consent to participate.
Bethesda, MarylandAges 2–100 - NCT05403151Recruiting
Healthy blood vessel and control study

Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
