Recruiting studies
- NCT04857528Recruiting
Testing HPV DNA in anal and cervical tumors
This trial checks whether tumor samples contain HPV DNA (genetic material from the HPV virus). The goal is to improve detection in anal and cervical cancers, especially in patients planning standard radiation treatment.
Chicago, IllinoisAges 18 years+ - NCT04299828Recruiting
Study of inflammation activity during complex heart surgery
This study measures how active white blood cells and inflammation are during complex heart surgery using a heart-lung machine. It may help doctors better understand what triggers inflammation during surgery and how to improve care.
Boston, MassachusettsAges Any age - NCT04772963Recruiting
Genetics study for brain blood vessel malformations
This study looks at genetic (inherited DNA) factors in people with certain abnormal blood vessel connections in the brain or spinal cord. It may help researchers understand why these malformations happen and how they might behave over time.
ParisAges Any age - NCT04809506Recruiting
Blood and genetic tests to predict future heart problems
This study looks for new body markers (including possible genetic traits) to better predict who is likely to have future cardiovascular events. Your results could help doctors estimate risk and choose prevention strategies more accurately.
ToulouseAges 18–99 - NCT04800458Recruiting
Testing antibody findings to confirm autoimmune low platelets
This study looks at blood test antibodies to help confirm whether low platelet counts are caused by an autoimmune condition. It may help doctors better classify your type of low platelets and guide appropriate next steps.

Study immune blood and spinal fluid cells in multiple sclerosis
This study looks at different immune cells in blood and, sometimes, spinal fluid (CSF) to understand what’s driving multiple sclerosis (MS) or early MS-like symptoms. Your participation may help researchers better explain the disease and potentially improve how it’s diagnosed or treated.
BordeauxAges 18 years+ - NCT04697095Recruiting
Testing immune cells from specific AMD eye types
This study collects immune cells (from a blood sample) from people with certain types of age-related macular degeneration (AMD) and compares how long they live. It may help researchers understand how immune-related changes relate to AMD outcomes.

Genetics study to find why HER2 breast cancer treatment varies
This study looks at genetic factors to understand why some people’s HER2-positive breast cancer responds better—or has more side effects—after treatment. Your info and possible past treatment history may help researchers improve how HER2 treatment is chosen and managed.
StrasbourgAges 18 years+ - NCT04556916Recruiting
Early prostate cancer screening with MRI before biopsy
This study is testing an approach to find prostate cancer earlier in men who may be at higher risk. If you fit the criteria, you may get an mpMRI scan before undergoing a prostate biopsy to check for cancer.
MontpellierAges 40 years+ - NCT04537390Recruiting
Measuring AMH hormone levels in healthy girls
This study measures a hormone called AMH in girls before and after puberty. It’s done while participants have a routine outpatient surgery, to better understand what AMH levels look like in healthy children.
Chicago, IllinoisAges Up to 18 years - NCT04393701Recruiting
Testing newborn blood spots to check for rare storage diseases
This pilot study tries a systematic way to look for several rare “lysosomal storage” diseases in newborns using a specialized lab test on routine blood samples. It may help detect these conditions earlier so treatment can start sooner if needed.
CaenAges 1 day–4 days - NCT04477928Recruiting
Checking type 1 diabetes risk using routine child care
This study estimates the chance of developing type 1 diabetes in children by using information gathered during regular well-child visits. It may help identify children who could benefit from earlier monitoring.
Bemidji, MinnesotaAges birth–17 years - NCT04429594Recruiting
Study tracking COVID-19 infection rates in the public
This study looks at how often SARS-CoV-2 (the virus that causes COVID-19) infection happens in people who may have been exposed in the community. It may help researchers understand infection rates and patterns in the general population.
NiceAges 18 years+ - NCT04427163Recruiting
Study of health differences using blood and data profiles
This study looks at how people’s health and disease risk show up in multiple types of information collected together (like blood-related measures and other data). It may help researchers understand what patterns are linked to health versus future disease.
OlomoucAges 18–68 - NCT04288635Recruiting
Testing a nutrient supplement for energy problems in septic shock
This study looks at whether a metabolite (nutrient) supplement can help the body’s cells work better when someone is in septic shock. It is done in the ICU, and it may benefit people with sepsis who still have poor circulation and high lactate levels despite standard treatment.
Angers, Maine et LoireAges 18 years+ - NCT04258293Recruiting
Diabetes screening for people taking steroid tablets long term
This trial checks whether people who take steroid medicines for more than 3 months are developing early diabetes, using blood tests before and around starting treatment. It may help catch diabetes sooner if it’s starting to develop, even in people who didn’t have diabetes yet.
DijonAges 18 years+ - NCT04326218Recruiting
Understanding Immune Causes of Kidney Membrane Disease
This study examines blood and kidney tissue samples from people with membranous nephropathy—a condition where the kidney's filtering membrane is damaged by the immune system. Researchers are trying to understand which immune markers predict how the disease will progress and respond to treatment.
Nice, Alpes MaritimeAges 18 years+ - NCT04261192Recruiting
Grow lab models of head and neck cancer to test treatments
This study collects tissue from people with newly diagnosed head and neck squamous cell cancer and grows “mini tumor models” in the lab. The goal is to see how these models respond to new therapies, which may help guide more effective treatment choices in the future.
CaenAges 18 years+ - NCT04202094Enrolling by invitation
Fertility options for young men after childhood cancer treatment
This study looks at fertility outcomes in young men who had cancer or blood disorders as children and then received high-risk treatment that can affect future fertility. It also compares people who did or did not store testicular tissue through a biopsy when they were younger.
BrusselsAges 18 years+ - NCT04165798Recruiting
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.
Gilbert, ArizonaAges 18 years+ - NCT03268668Recruiting
Study brain clot makeup and blood markers after stroke
This study looks at the composition of a stroke blood clot and compares it with blood test results to understand treatment response, stroke cause, and prognosis. It may help doctors better predict outcomes and improve care after ischemic stroke.

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 684 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.
