Recruiting studies
- NCT02579278Recruiting
Tests blood DNA and scans in early colon cancer surgery
This study looks at a blood test that detects cancer DNA (ctDNA) and compares it with CT scan findings before surgery. It may help doctors understand how aggressive the cancer is and how scan features relate to blood test results.

Immune registry for BK virus in kidney transplant patients
This study is creating a registry to learn how the immune system responds to BK virus in people who have recently received a kidney transplant from a deceased donor. Researchers hope this information will help improve treatment for BK virus infections.
Richmond, VirginiaAges 18 years+ - NCT05632432Recruiting
Heart tissue grafts to help the heart after surgery
This trial tests whether transplanting tiny heart “micrografts” from the left heart chamber area can improve heart function after cardiac surgery. It is meant for people with weakened heart pumping and heart failure symptoms despite medicine.
Helsinki, UusimaaAges 18–75 - NCT07280091Recruiting
Skin and gut bacteria in Netherton syndrome
This study looks at the bacteria on the skin and in the gut of people with Netherton syndrome, a condition that affects the skin barrier and often causes allergies. It also compares these findings to healthy volunteers to understand how the microbiome might be different.
Paris, Île-de-France RegionAges 10 years+ - NCT04274283Recruiting
Study of brain tumor samples and blood tests
This trial studies newly diagnosed or progressing brain tumors (grade 2–4 gliomas) to better understand the disease using tumor tissue and blood samples. It may help doctors learn which treatments could work best for different tumor types by matching tumor material to blood results.
BirminghamAges 16 years+ - NCT04421846Recruiting
Studying the causes of severe seizures and immune brain swelling
This study looks at what causes severe seizure episodes (“status epilepticus”) and a related immune condition that affects the brain (“dysimmune encephalitis”). The goal is to better understand the disease process, which may guide future care.
ParisAges 2 years+ - NCT06861244RecruitingPhase 2
ETMR brain tumor trial for children
This trial is for children with a rare brain tumor (ETMR) who have not had radiation. Depending on how much tumor is left after surgery and if it has spread, the study compares giving radiation early versus high-dose chemotherapy.
Birmingham, AlabamaAges Any age - NCT04690972Recruiting
Collection of blood and tissue samples for liver disease research
This study builds a research library of biological samples (like tissue and blood) from people with chronic liver disease. It aims to create better lab and preclinical models of tumors and long-term liver problems, which may help future treatments.
StrasbourgAges 18 years+ - NCT07035587Recruiting
A blood test to detect multiple cancers and monitor leftover tumors after treatment
This trial uses a blood test to find early signs of cancer or leftover tumor cells after treatment. It may help people with certain cancers or those with non-cancerous growths understand their condition better.
SeoulAges 19 years+ - NCT07358013Recruiting
Endothelial cells in von Willebrand disease and related conditions
This study looks at special cells from blood vessels (endothelial colony-forming cells) in people with von Willebrand disease (a bleeding disorder) or a related acquired condition. The goal is to better understand these conditions using blood donations.
MilanAges 16 years+ - NCT05772559Recruiting
Study of AML genes and drug response in young patients
This trial looks at how childhood, teen, and young adult acute myeloid leukemia (AML) changes at the genetic level and how cells respond to multiple drugs. It may help doctors understand which treatments work best and how leukemia interacts with supportive cells in the bone marrow.
AmiensAges Up to 25 years - NCT02168868Recruiting
Blood tests to find autism-related protein signals
This study looks at blood samples from children (and sometimes parents) to see if certain protein patterns can help identify or better understand autism spectrum disorder. The results could support finding “biomarkers,” which are measurable signs that may guide future research or care.
JerusalemAges 10 months–19 years - NCT06694363Recruiting
New test to guide treatment for APDS immune disorder
This study uses a new blood test to find and monitor people with APDS, a rare immune disease, who may be helped by the drug leniolisib. It aims to improve how doctors screen and track treatment response.
BordeauxAges 12 years+ - NCT06292598Recruiting
Gut bacteria and sleep disorder study
This study compares gut bacteria and substances from the gut in people with type 1 narcolepsy versus those without. It aims to understand how gut health might be linked to this sleep disorder.
Nîmes, GardAges 10 years+ - NCT05754892Recruiting
Using tumor lab markers during adrenal cancer care
This trial studies how to use lab tests (“molecular markers”) in routine clinical care to help manage people with adrenal tumors that could be cancerous. If you are having surgery soon (or recently), your tissue may be tested to see if these markers improve decision-making for your care.
ParisAges 18 years+ - NCT03819829Recruiting
Blood sampling study for healthy adults’ immune responses
This study takes small blood samples to learn how the immune system works in healthy people. It may help researchers better understand immune biology for future treatments, while you help by participating in regular research blood draws.
AmsterdamAges 36 years+ - NCT06365359Recruiting
Lupus and pesticide exposure in Martinique
This study looks at how exposure to a pesticide called chlordecone might affect people with lupus in Martinique. Researchers want to understand if there is a link between the chemical and lupus symptoms or kidney problems.
Fort-de-FranceAges 18 years+ - NCT06486909Recruiting
Shunt need after brain aneurysm bleed: role of early high blood sugar
This study looks at whether high blood sugar levels early after a brain aneurysm bleed affect the need for a shunt (a tube to drain fluid from the brain). It aims to help doctors understand who might need this treatment.
AarauAges 18 years+ - NCT04436991Recruiting
Testing antibiotic doses in older adults in the emergency room
This study looks at how best to dose certain antibiotics in people age 75 and older who are admitted to a geriatric (older-adult) hospital unit. It aims to measure antibiotic levels in the body to see whether dosing can be improved for older patients.

Common questions
- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 699 recruiting studies that include Blood sampling, 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 sampling 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 sampling 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 sampling or a specific trial is right for you.
