Summary

This study is testing a more accurate way to diagnose primary aldosteronism, a common but often missed cause of high blood pressure that can be cured with surgery. Researchers will measure urine aldosterone using a precise lab method (LC-MS/MS) in 800 healthy volunteers and patients after a three-day high-salt diet. The goal is to set a new diagnostic threshold that helps doctors identify this condition earlier and more reliably.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could lead to a more accurate diagnostic test for primary aldosteronism, helping doctors identify a curable cause of high blood pressure earlier.
What could go wrong: This is an early-stage diagnostic study, not a treatment trial. The new threshold may not prove significantly better than current methods, and results may not apply to all populations.
