Recruiting studies
- NCT06387030Recruiting
EoE biopsy study during endoscopy
This trial looks at taking a small tissue sample during a routine endoscopy to better understand eosinophilic esophagitis (EoE). It may help doctors learn how to diagnose and track EoE more easily.
ParisAges 2–17 - NCT06721455Recruiting
Blood Management Study for Pediatric Heart Surgery
This study looks at how managing blood products during heart surgery with a heart-lung machine affects the risk of red blood cell breakdown in children. The goal is to find safer ways to handle blood during these procedures.
Boston, MassachusettsAges birth–17 years - NCT07755007Recruiting
Blood sample tube transport comparison
This trial compares two ways of sending blood samples from an emergency room to the lab: quickly through a tube system or carried by staff. It checks if either method breaks red blood cells, which can affect test results, to see if the tube system is safe to use.
Istanbul, PendikAges 18 years+ - NCT04278404Recruiting
Drug safety study for children already on certain medicines
This study measures how certain medicines move through the body and checks their safety in children. It may help doctors better understand dosing and side effects in kids who are already receiving these treatments, or in some kids who recently tested positive for COVID-19.
Phoenix, ArizonaAges birth–20 years - NCT05627713Recruiting
Studying monkeypox infection and vaccine in adults
This study looks at the medical and lab changes in people with suspected or likely monkeypox, and in adults who may be eligible for a monkeypox vaccine. Your participation helps researchers understand how infection and vaccination affect the body and how to improve care.
ParisAges 18 years+ - NCT04593498Recruiting
Test for abnormal heart rhythm triggers for some heart rhythm types
This study looks at people who have frequent abnormal signals from the upper heart (supraventricular extra beats or short runs) and how that relates to atrial fibrillation risk. If you qualify, you may help researchers understand better ways to prevent or manage certain heart rhythm problems.
StockholmAges 70–89 - NCT04478409Recruiting
Test to screen Mediterranean family fever in children and adults
This study checks how well a specific blood test works for people who may have Mediterranean family fever (FMF). It may help doctors recognize FMF more accurately and decide on follow-up and treatment.
BronAges 4 years+ - NCT07422974Recruiting
Surgery results after pre-treatment for colorectal cancer
This study looks at how well patients recover from colorectal cancer surgery, comparing those who had chemotherapy or radiation before surgery to those who did not. The goal is to understand if pre-treatment affects surgical outcomes.
OsijekAges 18 years+ - NCT06084195Recruiting
Study of ovarian cancer using advanced imaging
This trial uses a special imaging technique to study high-grade serous ovarian cancer. It aims to better understand the tumor to improve treatment. If you have advanced ovarian cancer and are scheduled for surgery, you may be eligible.
MontpellierAges 18 years+ - NCT06144762Recruiting
Precision imaging for early detection and treatment monitoring in pancreatic cancer
This trial uses advanced imaging to detect pancreatic cancer early and track how well treatment is working. It may help if you have pancreatic cancer that can be surgically removed, either right away or after chemotherapy.
MontpellierAges 18 years+ - NCT06701890Recruiting
Traveler health study
This study follows travelers to learn about illnesses they might get abroad, like infections from mosquitoes or antibiotic-resistant germs. It uses a smartphone app to track your health before, during, and after your trip.
ParisAges 18 years+ - NCT07097480Recruiting
Study on virus spread from monkey bites to people
This study looks at whether viruses can be transmitted to people who have been bitten by a non-human primate (like a monkey). It aims to understand the risk and gather information that could help prevent infection.
ParisAges 18 years+ - NCT04898647Recruiting
Study of blood thickness in Waldenström’s disease
This study looks at “hyperviscosity,” meaning very thick blood, in people with Waldenström macroglobulinemia (WM). Your results may help doctors better understand who needs treatment and what tests should be used, even if thick blood is not found.
AmiensAges 18 years+ - NCT07007338Recruiting
Calcium bone balance in children on dialysis starting cinacalcet
This study looks at how a medicine called cinacalcet affects calcium in the bones of children on dialysis. It may help doctors better understand bone health for kids like yours.
BordeauxAges 3–17 - NCT05481502Recruiting
Study looks at immune markers after cell therapy
This study collects immune and tumor-related samples to learn what predicts response to adoptive cell therapy (a treatment using immune cells). If you (or your child) are eligible, you may help researchers understand who benefits and why.
Villejuif, Val De MarneAges 2 years+ - NCT06661564Recruiting
Testing tears for Alzheimer's disease diagnosis
This study looks at whether tears can help detect Alzheimer's disease. You will have your tears collected and tested for possible biomarkers.
Tours, FranceAges 18 years+ - NCT06544018Recruiting
Sleep and body clock study for CAPS patients and family members
This study looks at how CAPS (a genetic condition that causes inflammation) affects sleep and daily body rhythms. It compares people with CAPS to healthy family members living in the same home, to understand differences without any treatment being tested.
BronAges 6 years+ - NCT04265144Recruiting
Study group of adults with scleroderma for ongoing care research
This study follows adults with systemic scleroderma (also called scleroderma) to better understand the condition over time. You may be included if you meet specific diagnosis and blood-test requirements and can give informed consent.
BordeauxAges 18 years+ - NCT06387654Recruiting
Collection of skin samples for immune-related skin diseases
This study collects skin samples and medical information from people with skin conditions caused by their immune system. It helps researchers better understand these diseases and develop new treatments.

Brain chemistry study after surgery in older adults
This study looks at how brain “metabolomics” (small chemical signals in the brain/body) relate to thinking or mood problems that can happen after surgery in people age 65 and older. It may help doctors understand who is more likely to have these side effects after an operation.

Common questions
- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sampling, 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 sampling 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 sampling 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 sampling or a specific trial is right for you.
