Dr. Bob Centaur and Dr. Alexander Leung discuss a study challenging the necessity of confirmatory testing for primary aldosteronism. They highlight that traditional methods suffer from logical biases and fail to accurately identify false negatives. The study demonstrates that patients with positive screening tests benefit from treatment regardless of confirmatory results. Consequently, the 2025 Endocrine Society guidelines now recommend skipping confirmatory tests in favor of direct screening and empirical treatment.
