The Essential Tests for Diagnosing Primary Aldosteronism
Published: Feb 17, 2024
Diagnosing primary aldosteronism requires specific tests to confirm excessive aldosterone production. Learn which tests are crucial.
Initial Screening Tests
The first step in diagnosing primary aldosteronism involves screening tests like measuring plasma aldosterone concentration and plasma renin activity. A high aldosterone-to-renin ratio suggests an aldosterone-producing condition. These tests help pinpoint whether further diagnostic procedures are needed.
Confirmatory Testing
If initial screenings indicate potential primary aldosteronism, confirmatory tests like saline infusion or oral salt loading are performed. These tests assess aldosterone levels under controlled conditions to confirm overproduction. Proper preparation and interpretation are vital to avoid false results.
Imaging and Genetic Testing
Once biochemical tests suggest primary aldosteronism, imaging studies like CT scans help identify adrenal abnormalities. Genetic testing can also be done to find mutations linked to aldosterone overproduction. These tests guide treatment decisions, especially if surgery is considered.
