Simple blood test could uncover curable high blood pressure
NCT ID NCT05757076
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a simple blood test, called the aldosterone renin ratio (ARR), could help doctors find more cases of primary aldosteronism—a common but often missed cause of high blood pressure that can be cured with surgery or treated with specific medications. Researchers looked at 53 adults with high blood pressure to see how many cases were being overlooked. The goal is to improve detection so patients can get the right treatment sooner.

What this could lead to
If successful, this blood test could help doctors find more cases of primary aldosteronism, leading to better treatment or even a surgical cure for some patients.
What could go wrong
This was a small, completed study with only 53 participants, so results may not apply to everyone. The test may not catch all missed cases.
