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.

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.

Study of immune-related gut illnesses in adults
This study looks at adults with immune-related stomach and intestine problems to better understand what may cause them. If you qualify, you can share information and consent to help researchers learn how these conditions work.
CréteilAges 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 - 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+ - NCT04374175Recruiting
Blood sample bank for pancreatic cancer patients and controls
This study collects and stores blood samples (“serum bank”) from people with pancreatic cancer and from comparison participants. The goal is to help researchers study the disease and improve future diagnosis or treatment planning.
Saint-EtienneAges 18 years+ - NCT04377854Recruiting
Checking whether BNP predicts outcomes in advanced heart failure
This study looks at whether a blood test called BNP can help predict what happens over time in people being evaluated for advanced heart failure treatment. It may help doctors better plan care and follow-up for patients long-term.
Copenhagen, DKAges 18 years+ - NCT04377490Recruiting
Study of blood clots in hospitalized COVID-19 patients
This study looks at how often blood clot–related problems happen in people hospitalized with serious COVID-19 lung illness. It may help doctors understand risks and improve care for patients in the hospital.
AmiensAges 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 - NCT04417803Recruiting
Testing blood and tumor markers to guide lymphoma treatment
This study looks at “biomarkers” (measurable signs in your tumor and possibly blood) to understand your lymphoma’s genetic make-up. The goal is to see which markers may help doctors decide on treatment and timing.
DijonAges 18 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+ - 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 - NCT04514965Recruiting
Bezafibrate for primary biliary cholangitis patients
This trial studies whether bezafibrate, a medication, can help people with primary biliary cholangitis (PBC). You may be considered if your care team is already considering bezafibrate and you meet safety requirements.
Aarhus N, Central JutlandAges 18–99 - NCT04530890Recruiting
Testing blood tumor DNA in digestive and breast cancers
This study looks at a blood test for “circulating tumor DNA” (tiny pieces of cancer-related DNA in the blood). It may help doctors learn more about digestive, gynecologic, or breast cancers and how patients respond when treatment like chemotherapy or immunotherapy is needed.
PoitiersAges 18 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.

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 700 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.
