Better blood tests to diagnose a treatable form of high blood pressure

This research is testing whether a newer, more precise blood test method can help doctors better identify primary aldosteronism—a treatable form of high blood pressure caused by a hormone imbalance. The study compares blood test results from healthy people and patients suspected of having this condition to establish more accurate diagnostic guidelines. Better diagnosis means more people could get the right treatment sooner.

Primary aldosteronism is the most common cause of secondary hypertension (high blood pressure from an underlying medical condition), but it is often missed because current diagnostic tests are not accurate enough. This research aims to solve that problem by using advanced laboratory technology to create more reliable diagnostic thresholds, helping doctors identify and treat this curable cause of high blood pressure earlier.
