Comparing two ways to sample vein blood from the adrenal gland using an arm vein
Part of Hormones & metabolism clinical trials.
This trial tests whether using one small tube (catheter) in a vein in the arm is as effective as using two tubes to collect blood from the adrenal glands to help diagnose high blood pressure caused by hormone issues.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 70 years old.
- You have high blood pressure.
- Initial blood tests suggest your adrenal glands may be making too much aldosterone (a hormone that raises blood pressure).
- You agree to take part and sign a consent form.
- You are not allergic to iodine-based contrast dye used in imaging.
- You are not pregnant, breastfeeding, or planning pregnancy, and you do not have serious health problems like kidney failure or recent stroke/heart attack.
- You do not have a suspected adrenal gland tumor.

Other trials that look related to this one.
This trial compares different ways of doing adrenal vein sampling (a test to find which adrenal gland is causing high blood pressure). It aims to see if combining methods works better than using just one for people with primary aldosteronism.
This study compares a newer, less invasive PET/CT scan (using 68Ga-Pentixafor) to the standard adrenal vein sampling test to identify which adrenal gland is causing high blood pressure in people with primary aldosteronism. If you're considering surgery to remove a nodule on your adrenal gland, this trial may help determine the best approach.
This trial studies whether a specific treatment (related to spironolactone/aldosterone support) can improve how well your blood vessels work in people with primary aldosteronism. It may help reduce blood pressure risk by improving blood vessel health.
This trial measures hormone levels in blood during a procedure to treat high blood pressure caused by an adrenal gland problem. It may help doctors understand how the body responds during treatment.
This trial tests whether a treatment called SAAE can improve “ventricular remodeling,” meaning changes in the heart muscle, in people with primary aldosteronism (PA). It may help the heart work more efficiently by targeting the cause of high aldosterone levels.
This study tests a procedure that blocks tiny arteries in the adrenal gland to treat high blood pressure and low potassium caused by aldosteronism. It may be an option if you cannot take medications or cannot have surgery.
