“Exclusion tests” for primary aldosteronism
- Oral sodium loading test
- Saline infusion test
- Captopril challenge test
- Fludrocortisone with salt loading test
Though these tests were proposed as ‘confirmatory tests’ for primary aldosteronism, it was found that their negative predictive value was more than the positive predictive value.
