Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare the consistency of 24-hour urinary aldosterone in the diagnosis of primary aldosteronism by oral sodium loading test between the second day method and the third day method

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an exploratory and prospective study of 17 healthy controls and 15 patients with primary aldosteronism, in which each participant will receive a high-sodium diet for 3 days to conduct a confirmatory test for primary aldosteronism. The consistency between the 2-day and 3-day oral sodium loading test for the diagnosis of primary aldosteronism is compared by measuring the 24-hour urinary aldosterone levels of the participants on the second and third days of the high-sodium diet. The study aims to explore whether the 24-hour urinary aldosterone level on the second day can replace the 24-hour urinary aldosterone level on the third day for the diagnosis of primary aldosteronism.
