- NCT07182214Recruiting
Lung cancer detection using a blood test for early signs
This study uses a blood test to look for tiny genetic markers (miRNA and DNA methylation) that may help detect lung cancer early. If you have a lung nodule or mass found on a CT scan and haven't had treatment yet, you may be able to join.

Screening study for pancreatic cancer in inherited gene risk
This trial tests ways to screen people who have a family-passed (inherited) gene mutation linked to higher pancreatic cancer risk. The goal is to find pancreatic cancer earlier and improve how screening is done for people at increased risk.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05127980Recruiting
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.
BaselAges 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.

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.

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.

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.

ParisAges 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+ - 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 - 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 - NCT07455136Recruiting
Blood test for traumatic brain injury diagnosis and monitoring
This study is testing a new blood-based test to help doctors diagnose traumatic brain injury (TBI) and track recovery or complications. If you have had a head injury and a CT scan as part of your care, you may be able to join.
Sacramento, CaliforniaAges 18 years+ - NCT07436637Recruiting
Blood test for colorectal cancer screening
This trial is testing a blood test called Guardant Shield to see if it can effectively screen for colorectal cancer (a common cancer of the colon or rectum). If you're between 45 and 85 and overdue for a screening, this test could be a simpler alternative to colonoscopy or stool tests.
Miami, FloridaAges 45–85 - 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+ - 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 - 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+ - NCT04925349Recruiting
Study blood immune patterns in several rare brain diseases
This study looks at immune cells in blood to better understand rare brain conditions caused by genetic changes. It may help researchers understand why symptoms happen and how the immune system is involved.

Lipid metabolism study in ascending aortic aneurysm
This study looks at how fat metabolism and cell energy centers (mitochondria) work in patients having surgery for an ascending aortic aneurysm. It aims to understand differences between people with bicuspid or tricuspid aortic valves.
DijonAges 18 years+ - NCT05076500Recruiting
How radiotherapy changes a tumor’s immune response
This study looks at how a tumor’s immune system responds when you receive radiotherapy. It involves taking a planned pre-treatment biopsy so researchers can study immune and tumor changes and see if radiotherapy affects them.

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.
