Recruiting studies
- NCT07044713Recruiting
Fun activities for kids during blood tests
This trial tests if hand puppets, coloring books, or watching images can help children ages 3-6 feel less scared during blood draws. It's for healthy kids who need blood taken once.
Kilis, CentralAges 3–6 - 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+ - NCT05004233Recruiting
Antiplatelet treatment imaging test for stroke patients
This study uses special microscope imaging (transmission electron microscopy) to look at tiny changes in platelets before and after starting an antiplatelet medicine. It’s testing whether platelets show clear structural signs around the start of treatment for a specific type of stroke.
Saint-EtienneAges 18 years+ - NCT03419689Recruiting
Study checks blood and tumor markers in advanced ovarian cancer
This study looks at “biomarkers,” meaning measurable signals in blood and tumor tissue, in people with advanced ovarian-type cancers. The goal is to understand these markers and how they relate to the cancer, which may help guide future care.
Barrie, OntarioAges 18 years+ - NCT06482957Recruiting
Sarcoma Survivorship Study for Patients and Families
This study gathers information from people diagnosed with sarcoma (a bone or soft-tissue cancer) and their family members to learn what life is like after diagnosis. It is open to patients of any age, as well as their parents, caregivers, and older siblings.
Nashville, TennesseeAges Any age - NCT02577731Recruiting
Study of bone marrow changes after major injury or elective hip surgery
This trial studies how bone marrow and blood-making cells may behave after severe trauma or after elective (planned) hip surgery. It may help researchers understand why recovery can be harder in some people and guide better care.
Gainesville, FloridaAges 18 years+ - NCT05854368Recruiting
Blood tests to detect early stomach changes and cancer
This study looks for a blood “signature” that can spot early, risky stomach changes (before cancer) and stomach cancer. It may help clinicians diagnose earlier and decide who needs closer follow-up.
Boulogne-BillancourtAges 18 years+ - NCT05616130Recruiting
Study of abnormal blood immune activation after trauma or elective hip surgery
This study looks at how the body’s blood-related immune system “switches on” in unusual ways after a major injury or elective hip repair. The researchers hope this helps them understand who is at risk for complications and why, by measuring changes in your blood around the time of surgery or hospital treatment.
Gainesville, FloridaAges 18–100 - NCT04690660Recruiting
Study of high blood pressure after pregnancy
This study follows people who had high blood pressure during pregnancy and/or in the first two weeks after delivery. The goal is to better understand postpartum hypertension so care can be improved for mothers at higher risk.
BaselAges 18 years+ - NCT07358013Recruiting
Endothelial cells in von Willebrand disease and related conditions
This study looks at special cells from blood vessels (endothelial colony-forming cells) in people with von Willebrand disease (a bleeding disorder) or a related acquired condition. The goal is to better understand these conditions using blood donations.
MilanAges 16 years+ - NCT06701214Recruiting
Blood cell mutations and inflammation registry
This study collects blood samples and health information from people with certain unexplained blood cell changes or those at higher risk for them, to learn how these changes relate to inflammation and heart health.
Nashville, TennesseeAges 18 years+ - NCT05772559Recruiting
Study of AML genes and drug response in young patients
This trial looks at how childhood, teen, and young adult acute myeloid leukemia (AML) changes at the genetic level and how cells respond to multiple drugs. It may help doctors understand which treatments work best and how leukemia interacts with supportive cells in the bone marrow.
AmiensAges Up to 25 years - NCT06232668Recruiting
Studying the placenta in preeclampsia
This study looks at the placenta and the area where the baby meets the mother's body to understand preeclampsia, a serious pregnancy complication. If you are between 9 and 15 weeks pregnant with one baby and are already scheduled for a placenta test, you may be able to join.
Alicante, AlicanteAges 18 years+ - NCT07660029Recruiting
Smart home blood test study for rheumatoid arthritis
This study tests a smart home blood collection platform for people with rheumatoid arthritis. It aims to make remote monitoring easier by allowing you to collect blood samples at home using a smartphone or tablet.
LondonderryAges 18 years+ - NCT07134491Recruiting
B Cells in Kidney Transplant Rejection Study
This study looks at certain immune cells (B cells) in the blood and kidney to better understand antibody-mediated rejection in kidney transplant patients. It might help doctors find new ways to diagnose or treat this type of rejection.
ParisAges 18 years+ - NCT07664891Recruiting
Metabolism and surroundings in pancreatic cancer
This study looks at how the metabolism of pancreatic cancer cells affects their surroundings. It uses a biopsy (removing a small sample of tissue from a tumor in the pancreas, liver, or lung) to learn more about the cancer and guide treatment.
MarseilleAges 18 years+ - NCT05051722Recruiting
Test DNA blood and tissue markers to detect gynecologic cancers
This study looks for “methylated DNA markers” (special DNA patterns) to help detect endometrial, ovarian, and cervical cancers, and to support doctors around planned procedures. It may help find cancer earlier or better sort out who needs closer treatment.
Phoenix, ArizonaAges 18 years+ - NCT05324553Recruiting
Using patient tumor samples to build lab models
This study uses tumor tissue from real patients to create lab models that can help researchers test treatments. You might be able to join if you need a biopsy or surgery for care and it’s safe to collect a small amount of tissue for research.
Rochester, MinnesotaAges 18 years+ - NCT05390424Recruiting
Test dried blood spots for hepatitis and HIV
This study checks blood from a simple dried blood spot to screen for hepatitis B, hepatitis C, and HIV. It may help find infections early, which can allow earlier treatment.
AvranchesAges 18 years+ - NCT07487506Recruiting
Screening for communicable diseases in asylum seekers
This study tests a screening program for communicable diseases (like infections that can spread) in asylum seekers living in reception centers. The goal is to find and help people who might have these conditions early.
Negrar, VeronaAges 18 years+ - NCT04074720Recruiting
Collecting breast cancer tissue and blood samples

Pembrolizumab with or without chemotherapy for stage IV lung cancer
This trial tests whether pembrolizumab alone, or pembrolizumab plus chemotherapy, can treat stage IV non-small cell lung cancer. It may help shrink tumors and improve outcomes by boosting the immune system, with or without added chemotherapy.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 347 recruiting studies that include Blood collection, 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 collection 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 collection 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 collection or a specific trial is right for you.
