Brain and nerve connection in POTS and after infection
This study looks at why some people develop POTS (a condition that causes a fast heart rate and dizziness when standing) and if it's linked to how the brain and vagus nerve work together. It also includes people recovering from a serious infection and healthy volunteers for comparison.
Richmond, VirginiaAges 12–21 - NCT06854848Recruiting
Granulomatosis patient study with biological samples
This study collects medical data and biological samples from people diagnosed with systemic granulomatosis (a condition where tiny clumps of immune cells form in organs) to better understand the disease. It may help develop better treatments in the future.

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+ - NCT07218601RecruitingPhase 2
Using breath testing to track lung cancer treatment
This trial uses a special breath test (E-Nose) to monitor how well treatment is working in people with non-small cell lung cancer. You just breathe into a device, and it measures compounds in your breath.
Basking Ridge, New JerseyAges 18 years+ - 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+ - 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+ - NCT02168868Recruiting
Blood tests to find autism-related protein signals
This study looks at blood samples from children (and sometimes parents) to see if certain protein patterns can help identify or better understand autism spectrum disorder. The results could support finding “biomarkers,” which are measurable signs that may guide future research or care.
JerusalemAges 10 months–19 years - NCT07280091Recruiting
Skin and gut bacteria in Netherton syndrome
This study looks at the bacteria on the skin and in the gut of people with Netherton syndrome, a condition that affects the skin barrier and often causes allergies. It also compares these findings to healthy volunteers to understand how the microbiome might be different.
Paris, Île-de-France RegionAges 10 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+ - NCT06842316Recruiting
Study on cannabis-like compounds for inflammatory arthritis
This trial tests whether plant-based compounds similar to cannabis (called phytocannabinoids) can help calm inflammation and improve immune function in people with certain types of arthritis or autoimmune diseases like lupus or Sjögren's disease. It aims to offer a new way to treat these conditions without the 'high' of marijuana.
OrléansAges 18 years+ - 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 - NCT05595954Recruiting
Personalized anesthesia plan to protect the brain during heart surgery
This trial studies whether tailoring anesthesia and monitoring the brain’s blood-flow control during heart surgery can improve neurological outcomes (brain-related function and recovery). It may help by guiding anesthesia in a more individualized way and checking how well the brain is protected during the operation.
BaselAges 65 years+ - NCT03773887Recruiting
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.
LilleAges 18–70 - 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+ - NCT07273643Recruiting
Studying tiny particles in cord blood of very premature babies
This study looks at microscopic particles called extracellular vesicles in the umbilical cord blood of babies born before 28 weeks. Researchers want to see if these particles can help predict severe health problems or death, and eventually improve care for extremely premature newborns.
MontpellierAges birth–3 months - NCT07313007Recruiting

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 270 recruiting studies that include Blood sample 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 sample 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 sample 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 sample collection or a specific trial is right for you.
