Recruiting studies
- NCT06047106Recruiting
MRI study for kidney transplant from living donor
This study uses special MRI scans after a living-donor kidney transplant to check how well the kidney is working. It aims to see if MRI can help monitor kidney health without needing a biopsy.
LyonAges 18 years+ - NCT06048835Recruiting
Studying tumor cells in breast cancer patients
This trial looks at tumor cells in the blood of women with breast cancer to understand them better. It may help doctors learn more about how the disease spreads.
Pavia, LombardyAges 18–90 - NCT06057844Recruiting
PET scan to detect active blood clots
This study uses a special PET scan to see if it can detect active blood clots. It is looking for healthy volunteers to help test the imaging method, not people who already have a clot.
BrestAges 18 years+ - NCT06071286Recruiting
Study tracking DNA from tumors in advanced ovarian cancer
This study looks for cancer DNA in your blood to understand advanced ovarian cancer better. It helps doctors see how the disease changes over time and may improve future treatments.
RomaAges 18–80 - NCT06073171Recruiting
Genes and skin pattern study for cutis tricolor
This study looks at the genes of people with cutis tricolor, a rare skin condition with three colors, to understand what causes it. You and your parents (one affected, one not) can help by donating a blood sample for DNA analysis.

Growing lab-mini-tumors for ovarian cancer treatment choices
This trial uses a small piece of your cancer tissue (taken during surgery) to grow 'mini-tumors' in the lab. These help doctors find which treatments might work best for you. It is for people with advanced serous ovarian cancer.
RomaAges 18–80 - NCT06086704RecruitingPhase 2
PET/MRI scan for PR-positive breast cancer before surgery
This trial tests a new PET/MRI scan (using a special tracer called 18F-FFNP) to see how it images progesterone-receptor-positive breast cancer before surgery. You would get the scan and then have your planned surgery.
Madison, WisconsinAges 18 years+ - NCT06097156Recruiting
Automated blood test for breast cancer monitoring
This trial tests an automated device that prepares blood samples to detect cancer-related changes. It aims to improve how doctors monitor breast cancer that has spread, without needing a tissue biopsy every time.
MilanAges 18 years+ - NCT06102070Recruiting
Genetic study of severe infections
This study looks for genetic reasons why some people get very serious infections. If you or a family member has had a rare, severe infection, researchers will analyze your DNA to find genes that might make you more vulnerable.
Paris, Île-de-France RegionAges Any age - NCT06116903Recruiting
Detecting tumor signals in blood for glioblastoma
This study looks for genetic markers from tumor cells in your blood to see if they can help track glioblastoma progression. If you have glioblastoma and standard treatment has stopped working, this test might give your doctor more information about your cancer.
LimogesAges 18 years+ - NCT06133244Recruiting
Hand function in systemic sclerosis
This study looks at how systemic sclerosis (a condition that can cause hardening of the skin) affects hand function. It aims to understand the problems people face and find better ways to help.
UtrechtAges 18 years+ - NCT06147414Recruiting
Blood test for genetic disorders in pregnancy
This study tests a safer blood test to check for certain genetic disorders during pregnancy, instead of an invasive procedure like amniocentesis. It's for pregnant women who are at risk of passing on a known genetic condition.
ParisAges 18 years+ - NCT06155266Recruiting
Blood test to tell bacterial vs viral infection
This trial uses a simple blood test to help doctors quickly tell if your infection is caused by bacteria or a virus. It only requires a small extra blood sample taken during your regular emergency visit.
ParisAges 18 years+ - NCT06183632Recruiting
Lipid study in healthy blood donors
This research study looks at tiny particles in the blood called microparticles and their fat content. It aims to understand these particles in healthy people, which helps in future research on diseases.
DijonAges 18 years+ - NCT06191302Recruiting
Long COVID study in Denmark
This study follows people who were hospitalized for COVID-19 to learn more about long-term health effects (post-COVID conditions). It uses blood samples already collected during their hospital stay.
HvidovreAges 18 years+ - NCT06197204Recruiting
Finding biomarkers in Langerhans cell histiocytosis
This study is looking for adults with Langerhans cell histiocytosis (LCH) and also for adults with certain lung conditions (like cystic lung disease or emphysema) or healthy smokers to act as controls. The goal is to find biomarkers (signs in the body) that can help doctors diagnose LCH, predict how it will progress, and see how well treatment is working.
ParisAges 18 years+ - NCT06203496Recruiting
Monitoring brain tumors with blood tests
This trial studies whether a blood test can track the progress of a type of brain tumor called a grade 4 diffuse glioma. It may offer a less invasive way to monitor these tumors after surgery.
CaenAges 18 years+ - NCT06219135Recruiting
Testing a new method to find infection germs and best antibiotics
This trial is testing a new method (IDBIORIV) to quickly identify the germs causing sepsis and find the right antibiotic. It aims to help patients with a confirmed bloodstream infection get the most effective treatment faster.
BronAges 1 day+ - NCT06247826Recruiting
Why amivantamab stops working in certain lung cancers
This study looks at how and why lung cancers with a specific EGFR mutation (exon 20 insertion) become resistant to the drug amivantamab. It collects blood and tumor samples from patients whose cancer has progressed on amivantamab to better understand resistance.
BordeauxAges 18 years+ - NCT06259019Recruiting
Blood test during heart procedure to find disease markers
This trial uses a special device to take a small blood sample from your heart arteries during a planned procedure. It aims to find unique markers that could help doctors better understand and treat coronary artery disease.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 701 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.
