Recruiting studies
- NCT06478160Recruiting
Closed blood-sampling system for ICU patients
This trial is testing a new way to draw blood from an arterial line that may reduce infection and blood loss. It is for adults in the ICU who need an arterial line for several days.
Madrid, MadridAges 18 years+ - NCT06714474Recruiting
Virtual game for teaching blood draw skills to nursing students
This trial tests if a virtual simulation game helps nursing students learn how to draw blood from a vein. It may offer a new way to practice this skill before working with real patients.
Izmir, İzmirAges 18 years+ - NCT04599621Recruiting
Testing treatment for heart pain with anxiety or depression
This trial looks at people who have coronary artery disease and unstable or certain stable chest-pain symptoms, especially when anxiety or depressive symptoms are also present. The goal is to see how the study approach helps heart symptoms when mental health symptoms occur at the same time.
SamarkandAges Any age - NCT06666803Recruiting
Personalized profile of pancreatic tumors from biopsy samples
This study will take a close-up look at your pancreatic tumor by using a sample from a biopsy to create a personal profile. The goal is to understand your cancer better and maybe find the best treatment for you.
StrasbourgAges 18 years+ - NCT03299179Recruiting
Female hormones and brain blood flow during MRI
This study checks how female hormones may change blood flow in the brain. You may be asked to undergo an MRI scan while hormone levels are assessed.
GhentAges 18–25 - NCT07464600Recruiting
CRP testing to predict leaks after colon surgery
This trial checks if a simple blood test for CRP (a marker of inflammation) after colorectal surgery can help predict if a patient might develop a leak where the bowel is reconnected. If you are having planned colon or rectal surgery, this study might be for you.
AmiensAges 18 years+ - NCT04292067Recruiting
Study gut bacteria in people with arthritis
This study compares the gut microbiome (the bacteria in your intestines) in adults with spondyloarthritis or rheumatoid arthritis versus healthy adults. It aims to better describe differences that may help explain these diseases.
Boulogne-BillancourtAges 18 years+ - NCT04458792Recruiting
Builds a cancer blood-and-biomarker database after sarcoma treatment
This study collects information and blood samples from adults with sarcoma who had surgery and possibly radiation. The goal is to build a large dataset that helps researchers understand sarcoma better and improve future care.
Montpellier, HeraultAges 18 years+ - NCT04893564Recruiting
Testing blood DNA after 6 months of Waldenström treatment
This study looks at a blood test called circulating tumor DNA, measured after 6 months of treatment, to see how well it predicts outcomes in people with Waldenström macroglobulinemia. It may help doctors better judge who is responding and who may need treatment adjustments earlier.
AmiensAges 18 years+ - NCT05564026Recruiting
Study of DNA patterns in childhood germ cell tumors
This study looks at “molecular” (DNA-related) features of germ cell tumors in children and teens. It also follows patients over time, which can help researchers understand tumor patterns and improve future care.
Minneapolis, MinnesotaAges Any age - NCT05890781Recruiting
Study pediatric cancer using lab-made immune organoids
This trial uses special lab models (“immune organoids”) to study certain cancers in children and young people. It may help researchers learn what those cancers do and improve future treatment ideas.
VillejuifAges Up to 25 years - NCT06016569Recruiting
Breath test for early lung cancer in high-risk smokers
This study tests a new breath test to find early signs of lung cancer in people at high risk. It looks for cancer biomarkers in the air you breathe out. If you are a heavy smoker between 55 and 74, this trial may help detect lung cancer earlier.
BrnoAges 55–74 - NCT06031714Recruiting
Fetal cells in women with skin ulcers
This study looks at fetal cells that stay in a woman's body after pregnancy to see if they play a role in chronic skin ulcers. It includes women who have had a baby and have a venous, diabetic, sickle cell, or mixed ulcer, as well as healthy women for comparison.
Paris, Île-de-France RegionAges Any age - NCT06443268Recruiting
Stroke and quality of life study with caregivers
This study looks at quality of life for people who have had a recent stroke or mini-stroke, and their caregivers. You and a close relative or friend both take part in interviews and surveys over time.
Zurich, Canton of ZurichAges 18 years+ - NCT05678309Recruiting
Study to create a patient library for itch without a cause
This trial sets up a patient library for people who have itching with no clear underlying skin or medical cause. It aims to collect patient input and experiences to improve understanding and support for this condition.
BrestAges 18–99 - NCT04866329Recruiting
Study of stress and environmental exposures in IVF fertility
This study looks at how environmental exposures and stress-related “oxidant” changes may affect fertility outcomes in IVF for women. You may be invited if you are in your first IVF egg retrieval cycle and meet the study’s specific IVF setup rules.
ToursAges 18–43 - NCT03941080Recruiting
Study gut bacteria changes in advanced colorectal cancer
This study looks at how gut bacteria (the microbiome) change during treatment for colorectal cancer that has spread or cannot be removed. Researchers hope the findings may help improve understanding of how treatment works and how to tailor care.
AssenAges 18 years+ - NCT04074720Recruiting
Collecting breast cancer tissue and blood samples
This study collects tissue and/or blood samples from people with breast cancer to help future research. It may be useful if you’re already having surgery or another procedure as part of your treatment plan.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04520672Recruiting
Blood tests that look for circulating tumor cells in cancer
This study uses blood samples to look for tiny pieces of cancer cells called circulating tumor cells. Your results may help researchers understand how cancer cells spread and how cancer could be monitored over time.
BaselAges 18 years+ - NCT05605353Recruiting
Using gut bacteria to study pelvic cancers
This study looks at gut bacteria (and the chemicals they make) in people being treated for pelvic cancers. The goal is to understand what might be happening in the gut and how it could relate to pelvic cancer.

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