Recruiting studies
- NCT06451744Recruiting
Study of biomarkers in lichen planus
This study looks at people with lichen planus (a rash that can affect skin, mouth, or genitals) to find markers in cells and blood that may help understand the disease. If you have a new diagnosis or a flare-up, and you are not on strong immune-suppressing medicine, you may be able to join.
BesançonAges 18 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+ - NCT06695494Recruiting
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+ - NCT06718127Recruiting
Study of immune response to yellow fever vaccine
This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
ParisAges 18–65 - NCT07019857Recruiting
Thymus removal and immunity in infant heart surgery
This study looks at how removing the thymus gland during infant heart surgery affects the immune system. It compares babies who have their thymus removed with those who have heart surgery without removing it, and with babies having other types of surgery.
NantesAges Up to 6 months - NCT07046260Recruiting
Blood test study for early cancer detection
This study is testing a new blood test to help doctors find cancer earlier. If you are 45 or older and have symptoms that might be cancer, or were recently diagnosed with cancer, you may be able to join.
Coronado, CaliforniaAges 45 years+ - NCT07085611Recruiting
Studying vaccine and antibody protection in adults
This trial checks how well antibodies from COVID-19 or monkeypox vaccines or treatments work in adults. It helps researchers understand your protection level.
OrléansAges 18 years+ - NCT07167732Recruiting
CTNNB1 Syndrome Natural History Study
This study follows people with CTNNB1 syndrome over time to better understand the condition. It does not test any new treatment—just collects information to help future research.
SydneyAges Any age - NCT07328178Recruiting
Understanding IgE proteins in allergies and immune conditions
This study looks at IgE, a protein involved in allergic reactions, to better understand its role in different immune-related diseases. It aims to find out how different forms of IgE relate to health and disease, which may help improve diagnosis or treatment.
Leuven, Vlaams-BrabantAges 18 years+ - NCT07356570Recruiting
Post-COVID care tracking study for long-term symptoms
This study follows people with lasting or complex COVID-19 symptoms who are already in a specialized care program. It aims to better understand and improve recovery after COVID.
Pierre-BéniteAges 18 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 - 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 - NCT07427940Recruiting
Genetics and autism: a study of the omic profile
This study looks at the genetic and molecular profiles of children with autism spectrum disorder (ASD) to better understand the condition and find new treatments. It compares children with ASD who have no known genetic cause to those with a specific genetic syndrome.
MilanAges 3–15 - NCT07465848Recruiting
Testing telomere measurement to help diagnose lung cancer
This study uses a simple blood test to measure telomeres (parts of your DNA) to see if it can help detect lung cancer earlier. Researchers will compare results from people with lung cancer, heavy smokers, and low-risk individuals to improve diagnosis.
Elche, AlicanteAges 45 years+ - 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 - NCT05042830Recruiting
Tests how birch allergy in the nose affects allergy signals in blood
This study looks at people with a birch pollen allergy to see how exposure in the nose can change allergy-related blood signals. The results may help explain why symptoms can “boost” throughout the body after nasal allergen contact.
Vienna, State of ViennaAges 18–60 - 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.

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

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 270 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.
