ResumoSUMMARY The response of plasma aldosterone to fludrocortisone administration (400 μg 12‐hourly for 3 days) was studied in twenty‐two patients with primary hyperaldosteronism. No difference was observed in the response between those patients with an adrenal adenoma and those with bilateral adrenocortical hyperplasia, there being no significant change in plasma aldosterone levels across the test period. No separation between the groups was seen when basal plasma renin concentration was related to the aldosterone level following fludrocortisone. It is concluded that the test is of little value in the pre‐operative differentiation of these conditions. Twenty‐three patients with no demonstrable cause for their hypertension and four with elevated levels of plasma deoxycorticosterone were similarly studied for comparison. These groups demonstrated a normal fall in plasma aldosterone levels following fludrocortisone.
