ALDOSTERONE, URINE 24H

Aldosterone, Urine 24 Hours

What it is

The Aldosterone, Urine 24 Hours test measures the amount of aldosterone excreted in urine collected over a 24-hour period. Aldosterone is a hormone produced by the adrenal glands that helps regulate sodium, potassium, and water balance in the body. This test provides valuable information about adrenal gland function and electrolyte balance.

Uses

This test is commonly used to evaluate suspected adrenal disorders, including primary aldosteronism (Conn’s syndrome) and secondary aldosteronism due to kidney disease or other conditions. It helps in diagnosing the cause of high blood pressure, unexplained low potassium levels, and assessing overall adrenal function.

Symptoms That May Lead to the Test

Doctors may recommend the Aldosterone 24-hour urine test if a patient has resistant hypertension, persistent low potassium levels, muscle weakness, frequent urination, excessive thirst, or signs of adrenal gland disorders.

Abnormal Results

High aldosterone levels: May indicate primary hyperaldosteronism (Conn’s syndrome), adrenal tumors, or secondary causes such as kidney disease or heart failure.

Low aldosterone levels: May suggest Addison’s disease, adrenal insufficiency, or suppression due to certain medications.

Risks

This test carries no direct risks since it involves urine collection. The main inconvenience is ensuring accurate 24-hour urine collection. Errors in collection may affect test results.
