What is the Aldosterone Test?

The aldosterone test measures the levels of aldosterone, a hormone produced by the adrenal glands that regulates sodium and potassium balance and blood pressure. It plays a vital role in cardiovascular and kidney function. Doctors use this test to diagnose hormone imbalances and guide treatment decisions.

Why Order an Aldosterone Test?

Diagnosing Primary Aldosteronism (Conn’s Syndrome)
This test helps diagnose conditions where the adrenal glands produce too much aldosterone. Patients may experience high blood pressure and low potassium levels. The test guides treatment such as medications or surgery.

Evaluating Adrenal Gland Function
Doctors may use this test to evaluate adrenal hyperplasia or adrenal insufficiency. It helps determine if hormone levels are within normal range or if there’s dysfunction in hormone production.

Investigating Causes of Resistant Hypertension
Excess aldosterone can cause sodium retention and high blood pressure. The test helps identify whether hormonal imbalances are behind difficult-to-control hypertension.

Diagnosing Hypoaldosteronism
Low aldosterone levels may indicate Addison’s disease or adrenal damage. Symptoms include dehydration, salt cravings, and low blood pressure. This test confirms the diagnosis and helps guide treatment.

Assessing Electrolyte Imbalances
Aldosterone plays a key role in sodium and potassium regulation. Doctors use this test to understand symptoms like muscle cramps or irregular heartbeats that may be tied to hormone-driven electrolyte disturbances.

Importance
This test provides essential information about adrenal function and hormone balance. It supports diagnosis and management of hypertension, adrenal disorders, and metabolic imbalances.
