Normal Aldosterone Range
Many individuals undergoing hospital examinations encounter a test for aldosterone but are unfamiliar with its purpose. To better assess their overall health, they wish to understand the normal reference range for aldosterone levels. So, what is the normal aldosterone range?
Normal Aldosterone Range
Aldosterone primarily acts on the kidneys to promote sodium and water reabsorption, thereby regulating electrolyte balance and maintaining stable blood pressure. Its secretion is mainly controlled by the renin-angiotensin system, but is also modulated by serum electrolyte levels, adrenocorticotropic hormone (ACTH), catecholamines, and intravascular volume. The normal plasma aldosterone concentration is 1–5 ng/dL in the supine position and 5–15 ng/dL in the upright (standing) position. Using the conversion factor 1 ng/dL = 10 pg/mL, the corresponding normal ranges are 10–50 pg/mL (supine) and 50–150 pg/mL (upright). Aldosterone measurement is indicated when hypertension or hypotension is present; abnormal levels warrant further diagnostic evaluation and appropriate management.

Primary aldosteronism can be diagnosed by measuring serum aldosterone levels. When necessary, suppression tests (e.g., saline infusion test or oral sodium loading test) may be performed to determine whether aldosterone hypersecretion is autonomous (i.e., non-suppressible). For primary aldosteronism caused by an adrenal adenoma, surgical resection is typically curative. In cases of bilateral adrenal hyperplasia without a clearly identifiable focal lesion, medical management with aldosterone antagonists—such as spironolactone—is recommended when indicated.

In daily life, avoid spicy and irritating foods, drink plenty of water to support metabolic function, and engage in moderate outdoor physical activity to enhance immune function. We hope this information is helpful to you!
