Sample collection study in healthy volunteers
This study collects small samples of blood and cells from the inside of your mouth. Depending on your age, it may also collect bone marrow and skin (for research lab testing). It’s mainly about research planning and analysis rather than treating a disease.
Bethesda, MarylandAges 8–99 - NCT07037082Recruiting
Understanding menstrual cycles to improve women's health
This study tracks menstrual cycles and daily symptoms using a smart ring and home tests. It aims to better understand normal cycles and help detect health issues early.
MontpellierAges 18–39 - NCT05844865Recruiting
GI cancer study using a lab tumor model from your surgery
This study uses a special lab model made from tumor tissue taken during a planned standard cancer surgery. It tests how well the lab model can represent your cancer, which may help researchers improve future treatments.
Orange, CaliforniaAges 18 years+ - NCT05588154Recruiting
Donate blood and other samples to study blood cancers
This study asks healthy adults to provide blood, bone marrow (if needed), skin, saliva, and stool samples. Scientists use these samples to compare patterns related to myeloid (bone-marrow) blood cancers, which may help future research and tests.
Bethesda, MarylandAges 18–120 - NCT06914778Recruiting
How diabetes affects the eyes in South Wales
This study looks at how fat and sugar levels in the blood relate to different stages of eye damage in people with type 2 diabetes. It may help find new ways to treat or prevent vision loss.
Llanelli, WalesAges 18–80 - NCT07125079Recruiting
Studying immune cells and a new treatment for ARDS
This study looks at how the immune system responds in people with ARDS (a severe lung injury) and tests a new treatment called PIP-2 in the lab to see if it might help. It aims to better understand lung injury and find new ways to treat it.
Philadelphia, PennsylvaniaAges 21–90 - NCT00067054Recruiting
Collecting blood and samples for research
This study collects blood and other samples from healthy volunteers, children, and people with infectious diseases to help advance research. If you join, you may donate blood, urine, or skin samples that will be stored and used in future studies.
Bethesda, MarylandAges 3 years+ - NCT04698421Recruiting
Blood and tissue sample collection for rare autoimmune nerve diseases
This study collects biological samples (like blood or other specimens) from people with rare neurological conditions that may involve the immune system. Your samples may help researchers better understand these diseases.
ToulouseAges 6–99 - NCT07460154Recruiting
Structured review to improve COPD management
This trial tests a structured review process to help people with COPD who have needed multiple steroid pills in the past year. It aims to improve care and prevent future harm from the condition.
North ShieldsAges 35 years+ - NCT06857604Recruiting
Immune defects behind common blood diseases in young people
This study looks at how problems with the immune system might be linked to certain blood disorders in people under 25. The goal is to better understand what causes these conditions and find better ways to treat them.
Montreal, CanadaAges Up to 25 years - NCT00471250Recruiting
Donate lung samples to help future lung and airway research
This study collects lung fluid and tissue (and sometimes nasal or breath samples) to store for future research. It aims to understand lung and airway biology, and you may help by donating samples during a short procedure.
Bethesda, MarylandAges 5–100 - NCT03408964Recruiting

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 699 recruiting studies that include Blood sample, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood sample trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood sample an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood sample or a specific trial is right for you.
