Study immune response to COVID-19 and improve testing
This study looks at how the immune system in the body responds to different COVID-19 virus variants. It may help improve how COVID-19 is diagnosed by comparing people who are currently infected and those who are not.
ParisAges 18–65 - NCT07031817Recruiting
Using a blood test to better diagnose bipolar disorder
This trial tests a new medical device that uses a blood test to help doctors accurately diagnose bipolar disorder in people who were thought to have major depression. It aims to see if the device can tell the difference and improve treatment choices.

Compare belly-skin closure methods after kidney transplant surgery
This study looks at which abdominal wall (belly) closure technique helps reduce the chance of an incisional hernia after a kidney transplant. If you’re having a kidney transplant, it may help surgeons choose a method that lowers this complication for future patients.
ManchesterAges 18–70 - NCT06362538Recruiting
Heart health prevention program

This study looks at how taking biotin (a common vitamin) might interfere with routine blood tests. It is for healthy individuals who want to understand if their vitamin supplement could change their lab results.
CopenhagenAges 20–70 - NCT03512132Recruiting
Test HDL function in type 1 diabetes with kidney changes
This study looks at how well “good cholesterol” (HDL) works in people with type 1 diabetes, especially when kidney tests show early or more advanced damage. Researchers will compare different groups (normal, micro-, and macro-albumin in urine) to better understand HDL’s role and how it may relate to kidney health.
DijonAges 18 years+ - NCT03526822Recruiting
Study of new glioblastoma using MRI scans and lab markers
This study follows people newly diagnosed with glioblastoma to see how certain lab signals (MMP2 and MMP9) match up with MRI scan features. It may help doctors better understand the disease and how it appears on imaging, but it’s mainly observational.
MarseilleAges 18 years+ - NCT04005638Recruiting
Biobank for people with autoimmune blood cell disorders
This study collects and stores biological samples (a “biobank”) from people with autoimmune cytopenia, so researchers can learn more about the condition. If you qualify, your samples may help future studies and improve care, and it’s based on voluntary consent.
PessacAges 18 years+ - NCT04174066Recruiting
Study on kidney damage in children and adults with MGLS or FSGS
This trial collects medical data and blood/urine samples from patients with minimal change disease or focal segmental glomerulosclerosis (FSGS) to better understand how the immune system damages kidney cells.
NiceAges 1 year+ - NCT05456893Recruiting
Testing blood and stool markers in active ulcerative colitis treatments
This study checks biomarkers (signals in blood and/or stool) in adults with moderate-to-severe ulcerative colitis. It compares patients starting targeted medicines and looks for marker patterns that may reflect how the disease is behaving.
Nancy, LorraineAges 18 years+ - NCT05499091Recruiting
Study rare disease genetics using family and health data
This study tries to find genetic causes for rare diseases that are not yet understood. It uses a national rare-disease data bank and collects consent from patients and sometimes close family members.
AngersAges Any age - NCT05670158Recruiting
Testing blood immune markers after cochlear implantation
This study compares blood and fluid-related immune “profiles” after cochlear implant surgery versus another ear/middle-ear surgery group. It aims to learn which immune signals may be linked to hearing outcomes and recovery after implantation.
MontpellierAges 18 years+ - NCT06448403Recruiting
Alzheimer's assessment study with brain scans
This study uses brain scans (MRI and EEG) to better understand Alzheimer's disease. It compares people with MCI or Alzheimer's to healthy volunteers to see how the disease affects the brain.
Trondheim, TrønderlagAges 65 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 - NCT06618703Recruiting
Brain radiation in childhood: early hormone check
This study follows children who had brain radiation for cancer to check for early hormone changes. It aims to catch and treat any hormone problems sooner.
AngersAges 4–18 - NCT06626178Recruiting
AI for preventing smoking-related diseases
This study uses artificial intelligence to analyze CT scans and other health data to better identify people at risk for smoking-related diseases like lung cancer. Researchers hope to improve early detection and prevention.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 695 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
