Recruiting studies
- NCT06694766Recruiting
Yellow Fever Vaccine Safety and Immune Response in Pregnancy
This study gathers safety and antibody information from women who received their first yellow fever vaccine either during pregnancy or outside of pregnancy. It aims to better understand how the vaccine affects pregnant women and their babies.

Genomic testing for cancer of unknown primary
This trial is for people with cancer of unknown primary (CUP), meaning cancer that started in an unknown place in the body. It aims to use advanced genomic testing (looking at your tumor's DNA) on your stored tumor sample and blood to find clues about where the cancer began and possible treatment options.
Manchester, Greater ManchesterAges 16 years+ - NCT06636318Recruiting
Immune changes during 24-hour surgery call
This study looks at how being on call for 24 hours affects the immune system of surgery residents. The goal is to see if these long shifts change how the body fights infection.
Chicago, IllinoisAges 18 years+ - NCT06470997Recruiting
Biomarkers for hepatitis from immunotherapy
This study looks for certain markers in the blood that can help diagnose liver inflammation caused by immunotherapy. It aims to better understand this side effect and how to treat it.
Montpellier, FranceAges 18 years+ - NCT04280510Recruiting
Study of immune-related gut illnesses in adults
This study looks at adults with immune-related stomach and intestine problems to better understand what may cause them. If you qualify, you can share information and consent to help researchers learn how these conditions work.
CréteilAges 18 years+ - NCT04925349Recruiting

Studying natural immunity in COPD and in healthy adults
This study looks at how the body’s “innate” (first-line) immune system works in people with COPD compared with healthy volunteers. It may help researchers understand COPD inflammation and how immune responses could be targeted in the future.
EdinburghAges 18–77 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT04857528Recruiting
Testing HPV DNA in anal and cervical tumors
This trial checks whether tumor samples contain HPV DNA (genetic material from the HPV virus). The goal is to improve detection in anal and cervical cancers, especially in patients planning standard radiation treatment.
Chicago, IllinoisAges 18 years+ - NCT04537390Recruiting
Measuring AMH hormone levels in healthy girls
This study measures a hormone called AMH in girls before and after puberty. It’s done while participants have a routine outpatient surgery, to better understand what AMH levels look like in healthy children.
Chicago, IllinoisAges Up to 18 years - NCT02735824Recruiting
Genetic study of immune problems in children
This study looks for new genetic causes of immune system conditions that can run in families. If you join, researchers will collect health information (and usually samples) from children with immune concerns and from close relatives for comparison.
Zurich, Canton of ZurichAges Any age - NCT02534649Recruiting
Drug-matching trial for adults with cancer DNA changes
This trial looks for the specific DNA or tumor changes in your cancer and then matches you to a targeted drug plan. It’s meant for people with early cancer that has not already been treated in this study.
BayonneAges 18 years+ - NCT02051062Enrolling by invitationPhase 4
Blood-plasma study of botulism antitoxin in children
This trial studies how a botulism antitoxin (called BAT, heptavalent) moves through the body in children. It may help doctors better choose doses and timing for pediatric treatment by learning from blood samples after the first dose.
Ages 1 day–11 years - NCT01192048Recruiting
Study genetics in congenital heart disease
This study looks at how genes may contribute to congenital heart disease. It may help researchers better understand causes and risk in families like yours.
Columbus, OhioAges Any age - NCT05322343Recruiting
Study biobank and brain health in people age 55–80
This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
Bordeaux, BordeauxAges 55–80 - NCT06277466Recruiting
Gene changes and diabetes risk study
This study looks at how certain gene changes affect blood sugar control in type 2 diabetes and also in people who have had pancreas surgery. It compares these groups with healthy volunteers to see how genes influence the risk of diabetes.
XuzhouAges 25–70 - NCT05263804Recruiting
Study uses MRI and blood clues after ischemic stroke
This study looks for biological and imaging markers that may predict heart/vascular outcomes after an ischemic stroke. You may join if you are eligible for standard stroke treatment and can complete planned follow-up and MRI scans.
BronAges 18 years+ - NCT02861781Recruiting
Collecting body tissue samples during bariatric surgery
This study collects small tissue samples during planned weight-loss surgery to better understand metabolism and how insulin works in people with and without type 2 diabetes. You may help researchers by allowing their team to take these samples while you are already having surgery.
MontpellierAges 18–65 - NCT07755007Recruiting
Blood sample tube transport comparison
This trial compares two ways of sending blood samples from an emergency room to the lab: quickly through a tube system or carried by staff. It checks if either method breaks red blood cells, which can affect test results, to see if the tube system is safe to use.
Istanbul, PendikAges 18 years+ - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT01137643Recruiting

This trial collects tissue, blood, and other body fluid samples from people with blood-related cancers. The goal is to help researchers study these diseases by building a source of samples for future testing.
Chapel Hill, North CarolinaAges 18–120 - NCT06545227Recruiting
Early vs. Late Monitoring for Gestational Diabetes History
This study looks at whether checking blood sugar levels earlier or later in pregnancy is better for women who had gestational diabetes before. It aims to find the best time to start monitoring to help protect both mom and baby.

Can blood tests improve lung cancer screening in smokers with artery disease?
This study looks at whether certain blood tests can help find lung cancer early in people who have smoked for a long time and also have artery disease. The goal is to see if adding these tests to current screening methods can better identify those at highest risk.

Study links gut health, diet, and thinking and movement in seniors

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 269 recruiting studies that include Blood sample collection, 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 collection 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 collection 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 collection or a specific trial is right for you.
