Testing blood markers in autoimmune, vasculitis, and autoinflammation
This study looks at blood “biomarkers,” or measurable body signals, in people with autoimmune diseases, vasculitis, or autoinflammatory conditions. The goal is to better understand these illnesses and how they relate to disease activity.

Test of EBV CAR-T or TCR-T cells for nasopharyngeal cancer
This early-phase study tests personalized immune cells (EBV CAR-T or TCR-T) to treat nasopharyngeal cancer that has returned or spread. It aims to help the immune system find and attack the cancer after other treatments have not worked.

Blood test to help detect certain early pancreatic tumors
This study looks at a special analysis of your blood (called cfDNA fragmentomics) to help find and tell apart certain early pancreatic tumors. If you’re having surgery for one of the listed solid pancreatic tumors, this trial may use your blood samples to improve diagnosis.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06082661Recruiting
Blood collection for research study
This study collects a blood sample from healthy adults to help with research. You may be able to join if you meet basic health requirements and have not donated blood recently.
Orlando, FloridaAges 18 years+ - NCT06123975Recruiting
Adenomyosis and infertility: immune factors trial
This study tests if treating immune system factors can help women with adenomyosis who are having trouble getting pregnant. It aims to see if addressing these immune aspects improves pregnancy chances.
BeijingAges 18–40 - NCT06249308Recruiting
Liquid biopsy test for early ovarian cancer detection
This study is testing a blood test to see if it can catch ovarian cancer early. You may be eligible if you have been recently diagnosed with ovarian cancer and haven't started treatment yet.
Guangzhou, GuangdongAges 40–75 - NCT06350851Recruiting
New rapid test to help end river blindness
This study is testing a new rapid diagnostic test that aims to help eliminate onchocerciasis (river blindness). The test will be checked in people with different types of filarial worm infections (or no infection) to see how well it can tell them apart.
YaoundéAges 18 years+ - NCT06451575Recruiting
Blood Clots and Behçet's Disease Study
This study looks at how Behçet's disease affects blood clotting. If you have Behçet's disease and are between 18–70, you may help doctors understand why some people with Behçet's develop dangerous blood clots.
Erzurum, Üniversite MahallesiAges 18–70 - NCT06478121Recruiting
Understanding how genes affect beta cells
This study looks at how specific genetic changes affect beta cells, which make insulin. It may help people with rare genetic forms of diabetes or other beta cell disorders, and also needs healthy volunteers for comparison.
Exeter, DevonAges 6–99 - NCT06510868Recruiting
MDS risk study for NET patients before or after PRRT
This study looks at the risk of developing Myelodysplastic Syndrome (MDS), a blood disorder, in people with Neuroendocrine Tumors (NET) who are treated with Peptide Radionuclide Therapy (PRRT). It involves a simple blood test to check for genetic changes linked to MDS. Participating can help understand and potentially prevent this side effect.
Toronto, OntarioAges Any age - NCT06547099Recruiting
Understanding new blood markers in memory loss and dementia
This study is looking for older adults (60+) to help researchers better understand how to detect and track memory changes and dementia. Participants will provide blood samples and other health information over time to identify new markers that might help with early diagnosis.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 349 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.
