Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues. You might be offered a chance to help doctors understand why some people get longer or more intense symptoms from infectious mononucleosis.

Blood test study for cervical cancer biomarkers
This study is looking for markers in the blood of people with cervical cancer that might help doctors choose the best treatment. It is a feasibility study, meaning it aims to find out if this approach works before a larger trial.

Study looks for cancer clues in people at high risk for lung cancer
This study enrolls adults who are being checked for possible lung cancer because of concerning symptoms or a high-risk situation. It aims to find molecular (cell/DNA-related) predictors that may help doctors better recognize lung cancer earlier.
Nashville, TennesseeAges 18 years+ - NCT04133077Recruiting
Biobank study using tumor tissue to grow patient tumor models
This study takes small samples of your breast tumor tissue after (or during) treatment and grows them in lab animals to better study breast cancer. It may help researchers test future ideas for treating aggressive breast cancer types like triple-negative or Luminal B.

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 - 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 - 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+ - 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+ - NCT07232550Recruiting
Breathing study for children needing bronchoscopy
This study collects samples (like fluid from the lungs) during a planned bronchoscopy to look for new ways to understand and predict children's breathing problems. It might help if your child already needs this procedure for a medical reason.
WarsawAges Up to 17 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 - 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 - 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+ - NCT07063719Recruiting
Finding cell markers for rare eye diseases in adults
This study looks for biological markers in the blood or eye samples of people with rare eye diseases compared to healthy volunteers. It aims to better understand and diagnose these conditions.
ParisAges 18 years+ - 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+ - NCT06852755Recruiting
Finding markers to track menopause in women
This study looks for biological signs that can help monitor menopause. It may help women understand their menopause transition better.
New Taipei CityAges 20 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 - 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.
ParisAges 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+ - 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+ - NCT05743582Recruiting
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 - 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+ - NCT06451744Recruiting
Study of biomarkers in lichen planus

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.
