Recruiting studies
- NCT06621732Recruiting
Using RNA to diagnose mitochondrial disease
This trial checks if looking at RNA from blood or skin cells can help diagnose suspected mitochondrial disease. It may help people who have a genetic variant of uncertain significance thought to affect mitochondria.
Nice, Alpes-maritimesAges Any age - NCT07313007Recruiting
Gut bacteria chemicals in fatty liver disease
This study looks at whether the natural chemicals made by your gut bacteria from the food you eat could affect liver fat and health. If you have MASLD (a fatty liver condition), researchers want to measure these gut-produced substances to better understand the disease.
Pierre-BéniteAges 18–80 - NCT05014165Recruiting
Cord blood study for leukemia with stored birth samples
This study looks at leukemia “genetic clues” using special stored samples, including cord blood saved at birth. It may help researchers better understand leukemia biology and how common mutations may show up early.
Minneapolis, MinnesotaAges Up to 25 years - NCT05042830Recruiting
Tests how birch allergy in the nose affects allergy signals in blood
This study looks at people with a birch pollen allergy to see how exposure in the nose can change allergy-related blood signals. The results may help explain why symptoms can “boost” throughout the body after nasal allergen contact.
Vienna, State of ViennaAges 18–60 - NCT05306912Recruiting
Test gene analysis on liquid from a lung biopsy
This study looks at special lab tests (molecular analysis) done on liquid taken during a bronchoscopy to better understand lung nodules. It may help doctors learn more about what these nodules are, using samples from the procedure.
Toulouse, OccitanieAges 18 years+ - NCT05380414Recruiting
Study of advanced pancreatic cancer using tumor tissue profiles
This study looks at advanced or metastatic pancreatic cancer patients and uses stored tumor tissue to learn what may predict treatment outcomes. You may be able to join if you have had limited prior chemotherapy and can provide an archived tissue sample.
LyonAges 18 years+ - NCT07377084Recruiting
Study of chemicals in head and neck cancer samples
This study looks at the chemical signatures (metabolomics) in blood and tumor tissue from people with head and neck cancer. It aims to find markers that may help predict treatment response or tailor future care.
NiceAges 18 years+ - NCT06588322Recruiting
Detecting gene changes in blood of ovarian cancer patients on PARP inhibitor
This study looks for specific gene mutations in the blood of ovarian cancer patients who have a BRCA mutation and are starting first-line maintenance therapy with a PARP inhibitor called Olaparib. It aims to better understand how these mutations may affect treatment response.
AngersAges 18 years+ - NCT07012291Recruiting
Blood test for patients on blood thinners
This study tests a new blood test called ClotChek™ to see how well it works for people taking direct oral anticoagulants (DOACs), a type of blood thinner. You would give a blood sample, and the test may help doctors better monitor your medication.
Danbury, ConnecticutAges 18–80 - NCT07310537Recruiting
Liquid biopsy trial for colorectal cancer liver metastases
This study tests whether a simple blood sample from your finger can detect tumor DNA as well as a standard blood draw. It is designed for people with colorectal cancer that has spread to the liver and hasn't responded to treatment.
Rotterdam, South HollandAges 21 years+ - NCT05322343Recruiting
Study biobank and brain health in people age 55–80
This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
Bordeaux, BordeauxAges 55–80 - NCT00898313Recruiting
Study looks for cancer clues in people at high risk for lung cancer
This study enrolls adults who are being checked for possible lung cancer because of concerning symptoms or a high-risk situation. It aims to find molecular (cell/DNA-related) predictors that may help doctors better recognize lung cancer earlier.
Nashville, TennesseeAges 18 years+ - NCT06131775Recruiting
Study of immune cells in blood of people with solid tumors
This study is looking at a specific type of immune cell (called TLR4+ cells) in the blood of people with solid tumors. By studying these cells, researchers hope to learn more about how the immune system reacts to cancer and to treatments.
BronAges 18 years+ - NCT07084558Recruiting
Testing treatment guided by tumor DNA for hormone positive breast cancer
This trial tests whether using a blood test (circulating tumor DNA) can help guide chemo and hormone therapy for early-stage, hormone receptor positive and HER2 negative breast cancer. The goal is to tailor treatment to your tumor's response, potentially reducing unnecessary side effects.
Vienna, AustriaAges 18–100 - NCT04133077Recruiting
Biobank study using tumor tissue to grow patient tumor models
This study takes small samples of your breast tumor tissue after (or during) treatment and grows them in lab animals to better study breast cancer. It may help researchers test future ideas for treating aggressive breast cancer types like triple-negative or Luminal B.
Clermont-Ferrand, Puy-de-DômeAges 18 years+ - NCT03773159Recruiting
Testing a blood clot test using whole blood flow
This trial tests a new lab device that measures how well your body forms primary blood clots while blood is kept in flowing conditions. It may help doctors better assess bleeding or clotting tendencies and guide future care.
BesançonAges 18 years+ - NCT04224064Recruiting
Blood test to help diagnose and predict liposarcoma
This study looks for a new blood test marker that may help doctors diagnose liposarcoma and estimate how it may behave over time. You may be asked for a blood sample and consent, and the study may follow you to see how well the test works.
MontpellierAges 18 years+ - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT05952648Recruiting
Test for pneumonia in ICU using fast DNA testing
This study checks whether a fast “DNA test” can help diagnose hospital-acquired or ventilator-associated pneumonia in very sick patients with sepsis. If the test is accurate, it may help doctors start the right treatment sooner.
BolognaAges 18 years+ - NCT07399327Recruiting
SEEG thermocoagulation for hard-to-treat epilepsy
This study is looking at how well a procedure called SEEG thermocoagulation (a way to stop seizures by heating a small area of brain tissue) works for people with epilepsy that doesn't improve with medication. By joining, you will help doctors understand why this treatment works for some people and not others.
MarseilleAges 12 years+ - NCT07398170Recruiting
Searching for tumor cells in fluid for recurrent meningioma

This study looks at whether a simple blood test can help guide the care of people being evaluated for colorectal cancer. It may support earlier or clearer decision-making alongside existing screening or colonoscopy results.
BesançonAges 18 years+ - NCT01763125Recruiting
Tumor bank trial for storing your blood sample
This study sets up a “tumor bank,” which means storing and later using your blood sample for future cancer research (or inflammatory disease research). You may be able to join if you currently have exactly one diagnosis—either a cancer or an inflammation condition.

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.
