Recruiting studies
- NCT05383339Recruiting
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.
Paris, FranceAges 18 years+ - NCT06804057Recruiting
SLE drug safety registry for adults with lupus
This registry tracks the safety and effectiveness of lupus treatments over time. If you have SLE and are starting a new treatment or were recently diagnosed, joining helps doctors learn which medicines work best.
Waltham, MassachusettsAges 18 years+ - NCT05750849Recruiting
Checks progesterone levels to predict pregnancy in fertility treatment
This study looks at whether a blood progesterone level around the time of a pregnancy test during fertility treatment helps predict which patients will have an ongoing pregnancy. It may help doctors better understand who is most likely to continue developing a pregnancy during artificial cycles.
Valencia, ValenciaAges 18–50 - NCT06716242Recruiting
A blood test to predict preeclampsia early in pregnancy
This study aims to see if a new blood test can help predict preeclampsia, a serious condition that can occur during pregnancy. It may help identify risk early so that you and your baby can receive the right care.
Alicante, AlicanteAges 18 years+ - NCT06680843Recruiting
Immune signatures from animal virus exposure in Cambodia
This study aims to understand how people's immune systems respond to viruses that spread from animals to humans (zoonotic viruses). If you have had recent contact with potentially infected animals in Cambodia, your participation can help researchers find ways to detect and prevent future outbreaks.
BattambangAges 18–65 - NCT06607055Recruiting
Immune markers in ICU patients with pneumonia
This study looks at how the immune system reacts in ICU patients on a ventilator who have pneumonia. By measuring immune markers, the researchers hope to better understand and predict complications like ventilator-associated pneumonia.
Aix-en-ProvenceAges 18 years+ - NCT06616363Recruiting
Brain and nerve connection in POTS and after infection
This study looks at why some people develop POTS (a condition that causes a fast heart rate and dizziness when standing) and if it's linked to how the brain and vagus nerve work together. It also includes people recovering from a serious infection and healthy volunteers for comparison.
Richmond, VirginiaAges 12–21 - NCT06574373Recruiting
Finding new markers for pancreatic IPMN progression
This study looks for new markers in the blood or tissues of people with a pancreatic condition called IPMN. The goal is to find better ways to predict if IPMN might turn into cancer and to help choose the best treatment.
RomaAges 18 years+ - 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.
St Louis, MissouriAges 60 years+ - NCT06508138Enrolling by invitationPhase 1
HPV vaccine study for healthy relatives of patients
This trial tests two experimental vaccines to boost the immune system against HPV 16. Healthy relatives of patients with HPV 16 cancer receive the vaccines, then donate blood cells for research.
Baltimore, MarylandAges 18–70 - 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 - 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 - NCT01205815Recruiting
Use and storage of leftover melanoma tissue for future testing
This study collects and stores leftover melanoma tissue (and sometimes blood) for future research and testing. If the trial uses your stored samples to help match treatments, it could support better care planning over time.
Nashville, TennesseeAges 18 years+ - NCT05847855Recruiting
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+ - NCT05844865Recruiting
GI cancer study using a lab tumor model from your surgery
This study uses a special lab model made from tumor tissue taken during a planned standard cancer surgery. It tests how well the lab model can represent your cancer, which may help researchers improve future treatments.
Orange, CaliforniaAges 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 - NCT03420118Recruiting
Study of tumor and blood markers in gynecologic cancers
This study looks at tumor tissue and blood samples to find biological “markers” in people with gynecologic cancers. It may help researchers understand disease better and could guide future, more personalized treatments.
Toronto, OntarioAges 18 years+ - NCT05587543RecruitingEarly Phase 1
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.
ShanghaiAges 18–75 - NCT05540561Recruiting
Testing and monitoring for nitrous oxide use
This study looks at how nitrous oxide (also called laughing gas) is detected and how health effects may show up over time. It may help doctors better diagnose problems early and track changes after use.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 338 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.
