Blood Cell Collection Study for Immune and Blood Disorders
This study collects blood cells and bone marrow from people with immune system or blood disorders, and from healthy volunteers. Researchers will study these cells and may convert them into special stem cells (iPS cells) to better understand diseases and develop treatments.
Bethesda, MarylandAges 18–70 - NCT00032513Recruiting
Genetic study of chronic active Epstein-Barr virus disease
This research study looks for genetic factors that may explain why some people develop severe, long-lasting Epstein-Barr virus (EBV) infection. Researchers will study blood and tissue samples from patients with this rare condition, their healthy relatives, and unrelated volunteers to understand the disease better.
Bethesda, MarylandAges 1–120 - NCT00923442Enrolling by invitation
Study of blood cancers’ biology using stored or new tissue
This trial studies how different blood cancers and early (pre-cancer) blood conditions work, using tumor/blood tissue samples. It may help researchers learn more about disease biology for future treatments, with little to no extra risk if samples come from routine care.
Bethesda, MarylandAges 1–120 - 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 - NCT00867269Recruiting
Study of causes and progression of low CD4 blood cells
This study looks for what causes and how idiopathic low CD4 cells happen over time, using blood and tissue samples. It may help doctors learn why this occurs and how to better track people with it.
Bethesda, MarylandAges 18 years+ - NCT00005917Recruiting
Understanding Chediak-Higashi Syndrome: A Research Study
This study helps researchers understand Chediak-Higashi syndrome, a rare genetic condition that affects how the body fights infections and controls bleeding. Participation involves medical evaluation and may help guide future treatments.
Bethesda, MarylandAges 1 month–70 years - NCT00047996Enrolling by invitation
Blood Donation Study for Blood Vessel Research
This study collects blood and urine samples from adults to help researchers understand diseases affecting blood vessels. Your donation helps scientists develop better treatments.
Bethesda, MarylandAges 18–100 - NCT00006150Recruiting
Understanding Hyper-IgE Syndrome: Natural History and Genetics
This study follows people with or suspected Hyper-IgE syndrome (a rare immune disorder causing repeated infections and skin problems) to understand how the condition develops, how best to manage it, and which genes are involved. Researchers also welcome healthy relatives of patients to help identify genetic patterns.
Bethesda, MarylandAges 1 month–120 years - NCT00923507Recruiting
Study of blood cancers’ natural course and next treatment needs
This study follows people with certain slow-growing blood cancers (CLL/SLL, LPL/WM, and related conditions) to understand how they progress and what leads to needing treatment. It may help doctors predict changes over time and plan care more effectively.
Bethesda, MarylandAges 18–110 - NCT00001465Recruiting
Study of lymphangioleiomyomatosis (LAM) disease process
This study looks at the natural history and disease process of lymphangioleiomyomatosis (LAM), a rare lung disease that mostly affects women. It may help understand how LAM progresses and how it affects daily life, and may include exercise testing and other evaluations.
Bethesda, MarylandAges 16–100 - NCT00471250Recruiting
Lung fluid and tissue sample collection for research
This study collects samples from your lungs and airways to help researchers better understand lung diseases. It is not a treatment study, but your participation could help improve future care for people with lung conditions.
Bethesda, MarylandAges 5–100 - NCT01174108RecruitingPhase 2
Stem cell transplant with donor T-cells for severe bone marrow failure
This Phase 2 study tests a specific type of donor stem cell transplant for severe bone marrow failure conditions, aiming to improve cure rates while reducing transplant risks. It includes people with diseases like severe aplastic anemia and certain bone marrow disorders, especially when standard transplant plans feel too risky.

Common questions
- How many blood & lymphatic clinical trials are recruiting?
- Clin2 is tracking 4,932 recruiting hematology studies from the U.S. registry right now, out of 7,407 we cover in this area in total.
- What does “Blood & lymphatic” cover here?
- Anemia, clotting disorders, and other conditions of the blood and lymphatic system. We group each study into blood & lymphatic based on the conditions it studies, so you can scan the whole therapeutic area at once and drill into a specific condition.
- How do I find a blood & lymphatic trial near me?
- Use the search to filter blood & lymphatic studies by location and eligibility. Every Clin2 trial page explains the criteria in plain English and offers a short, optional pre-screen for a fit read — the study team makes the final decision.
