Recruiting studies
- 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.

This study uses a simple blood test to quickly detect Alzheimer's-related brain changes (amyloid plaques). It may help people with memory concerns avoid a more invasive PET scan and get answers faster.
Hefei, AnhuiAges 45–85 - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 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+ - NCT07435467Recruiting
Blood tests for brain health in older hospital patients
This trial looks at how blood biomarkers relate to thinking, daily function, and survival in older adults, including those with neurological issues or dementia. It aims to improve understanding and care for hospitalized seniors.
AnconaAges 65 years+ - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT05567289Recruiting
Precision medicine after stem cell transplant
This study looks at a personalized (“precision”) approach for people who have received a stem cell transplant from a donor. It may help doctors better tailor care after transplant, especially for children.
ManchesterAges Any age - NCT01336855Recruiting
Provide blood for studies comparing HIV groups
This study collects blood to help researchers run multiple projects, including comparing people who are HIV-negative with people who have HIV. It may help advance knowledge that could improve future testing or treatments.
San Francisco, CaliforniaAges 18 years+ - NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT06474104Recruiting
Blood and skin sample collection for mitochondrial disease
This study collects blood and skin samples from people with primary mitochondrial disease and from healthy volunteers. The samples will help researchers better understand these diseases and develop future treatments.
Ramat Gan, IsraelAges 3–85 - NCT07197723Recruiting
Study of decision making about prostate cancer risk
This study looks at how men with a BRCA1/2 gene change make decisions about their health and prostate cancer risk. Participants will fill out surveys to help researchers understand these choices.
New York, New YorkAges 45–70 - 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+ - 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+ - 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+ - NCT07313007Recruiting
Gut bacteria chemicals in fatty liver disease
This study looks at whether the natural chemicals made by your gut bacteria from the food you eat could affect liver fat and health. If you have MASLD (a fatty liver condition), researchers want to measure these gut-produced substances to better understand the disease.
Pierre-BéniteAges 18–80 - 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+ - 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.
Clermont-Ferrand, Puy-de-DômeAges 18 years+ - NCT07743021Recruiting
Blood sample study for better health screening
This study collects blood samples and health information over time to improve early detection of diseases. It may help researchers find ways to prevent serious conditions.
BalatonfüredAges 40 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 - 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.

New imaging agent for advanced solid tumors
This trial tests a new imaging agent (18F-TRX) to see if it can better detect cancer spread in people with advanced solid tumors. It is designed for patients with specific cancers like high-grade brain tumors, advanced kidney cancer, or prostate cancer that has stopped responding to hormone therapy.
San Francisco, CaliforniaAges 18 years+ - NCT03124303Recruiting
Testing ways to measure and prevent delirium after surgery
This study looks at interventions to help with “postoperative delirium,” a sudden confusion that can happen after surgery, and uses brain measures like EEG and optional MRI. It may help doctors identify who is at risk and learn what approaches are most helpful after surgery.
Madison, WisconsinAges 60 years+ - NCT03818412Recruiting
Liquid biopsy for soft tissue sarcoma
This study checks if a blood test can detect DNA from soft tissue sarcomas. The goal is to see if circulating tumor DNA can help doctors monitor the disease and plan treatment.
Toronto, OntarioAges 18 years+ - NCT04280510Recruiting

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 347 recruiting studies that include Blood 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 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 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 collection or a specific trial is right for you.
