Better MRI and blood tests for glioblastoma treatment response
This study is testing whether special MRI scans and blood tests can help tell the difference between true tumor growth (progression) and a treatment-related reaction called 'pseudoprogression' in people with glioblastoma. The goal is to make treatment decisions more accurate.

Blood test for leftover cancer DNA after head and neck cancer treatment
This study uses a simple blood test to look for leftover cancer DNA after treatment for head and neck squamous cell carcinoma. The goal is to see if the test can find very small amounts of cancer early, which might help doctors make better decisions about follow-up care.
San Francisco, CaliforniaAges 18 years+ - NCT06633224Recruiting
Fatigue and biology in cancer patients getting chemoradiation
This study looks at why some people feel very tired during cancer treatment. Researchers will collect blood and stool samples to study how the body responds to chemotherapy and radiation.

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+ - NCT06545227Recruiting
Early vs. Late Monitoring for Gestational Diabetes History
This study looks at whether checking blood sugar levels earlier or later in pregnancy is better for women who had gestational diabetes before. It aims to find the best time to start monitoring to help protect both mom and baby.

Study of liver inflammation and healing in alcohol-related liver disease
This study compares patterns of liver inflammation and the liver’s healing ability in people with alcohol-related liver disease, using blood tests and (in most cases) a liver tissue sample. It may help doctors better understand what is happening in the liver and how it may recover.

30-year follow-up of the EGEA asthma study
This study invites people who took part in a previous EGEA survey to return for a 30-year check-up. The goal is to track long-term health changes related to asthma and allergies.

This trial collects blood and tissue samples from people with and without heart disease to study heart health. If you are 18 or older and either a UCSF patient, a family member of a heart patient, or have no heart disease, you may be able to help.
San Francisco, CaliforniaAges 18 years+ - NCT03756649Enrolling by invitation
IBD biobank study for adults and young adults
This study collects and stores information and samples from people with inflammatory bowel disease (IBD) to help researchers learn more and improve care. Your participation mainly helps build a “biobank,” which can support future studies.
Rochester, MinnesotaAges 18–85 - NCT00047996Enrolling by invitation
Blood Donation Study for Blood Vessel Research
This study collects blood and urine samples from adults to help researchers understand diseases affecting blood vessels. Your donation helps scientists develop better treatments.
Bethesda, MarylandAges 18–100 - NCT04615988Recruiting
Vitamin D levels and hormone side effects from immune cancer therapy
This study looks at whether your blood vitamin D level is linked to hormone-related side effects caused by immune checkpoint cancer drugs. It may help doctors better predict who is at risk and how to monitor patients during treatment.
New York, New YorkAges 18 years+ - NCT07353502Recruiting
Early Alzheimer's brain connection study
This study looks at a specific brain pathway that may be linked to early memory loss in Alzheimer's disease. It compares people with early Alzheimer's to healthy older adults to understand how connections between brain cells start to break down.
Yiwu, ZhejiangAges 50 years+ - NCT07712445Recruiting
Testing a clot-busting drug coated with platelet membranes
This study tests a new way to deliver a clot-dissolving drug called tenecteplase. The drug is coated with platelet membranes to target blood clots in arteries. It may offer a safer, more effective treatment for heart attack patients and is also enrolling healthy volunteers for comparison.
Nanjing, JiangsuAges 18–75 - NCT05571579Recruiting
Collecting blood and tissue samples from confirmed brain tumors
This study collects biological samples from adults with a confirmed brain tumor. Samples may help researchers better understand brain tumors and improve future treatments.
Bron, RhôneAges 18 years+ - NCT06129253Recruiting
GLOBE-HPV: Study of HPV in communities
This study is trying to find out how many people in different communities have HPV (human papillomavirus). It involves collecting samples and answering questions to help estimate the global burden of HPV.
DhakaAges 9–50 - NCT07075107Recruiting
Using cell and blood tests to find causes of rare developmental disorders
This study is looking for people with rare, unexplained conditions that cause early intellectual disability and low muscle tone. Researchers want to study your cells and blood to try to find new genetic causes that standard DNA tests missed.
Marseille, Provence-Alpes-Côt-d'AzueAges birth–99 years - NCT06806709Recruiting
Testing a needle-less device to reduce blood culture contamination
This study tests a device called PIVO to see if it can reduce contamination when taking blood samples to check for bloodstream infections. If you need a blood culture (a test to find germs in your blood) and have a small IV line (22 gauge or larger), you may be able to join this study.
Caboolture, QueenslandAges 18 years+ - NCT06042803Recruiting
Study on medicine levels in breastmilk

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 348 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.
