Testing a new blood test method to diagnose a treatable form of high blood pressure

This research study is testing whether a steroid-based blood screening method can more accurately detect primary aldosteronism—a specific type of high blood pressure that may be curable—in people who are already taking blood pressure medications. Right now, doctors typically ask patients to stop or switch their medications before screening, which can be risky and complicated. This study wants to see if the new blood test method works better while patients stay on their regular medications.

Many people with high blood pressure actually have a treatable form called primary aldosteronism, but it often goes undiagnosed because current screening requires stopping medications, which can be unsafe. This trial aims to develop a simpler, safer screening method that works while patients continue taking their regular blood pressure drugs.
