Aldosterone

ALDOSTERONE Test Purpose

This Test is performed to measure the level of aldosterone, a hormone produced by the adrenal glands that helps regulate blood pressure, sodium, and potassium balance in the body. Primarily, the test is used to evaluate adrenal gland function and diagnose conditions such as primary aldosteronism (Conn's syndrome), secondary aldosteronism, and adrenal insufficiency. Additionally, it assists healthcare providers in investigating unexplained high blood pressure, low potassium levels, and other electrolyte abnormalities. Furthermore, the test is often performed alongside Plasma Renin testing to calculate the Aldosterone-to-Renin Ratio (ARR), which helps identify hormone-related causes of hypertension. Moreover, the results are interpreted together with clinical findings, medical history, and additional laboratory investigations to provide a comprehensive assessment of adrenal health.

ALDOSTERONE Test is Recommended for Individuals:

• Individuals with high blood pressure that is difficult to control.
• Patients with suspected primary aldosteronism (Conn's syndrome).
• Individuals with low potassium (hypokalemia) without an obvious cause.
• People with early-onset hypertension, especially before 40 years of age.
• Patients with an adrenal gland nodule (adrenal incidentaloma).
• Individuals with a family history of primary aldosteronism or early-onset hypertension.
• Patients experiencing muscle weakness, fatigue, cramps, or excessive thirst related to electrolyte imbalance.
• Individuals undergoing evaluation for secondary causes of hypertension.
• Anyone advised by an endocrinologist or healthcare provider to assess adrenal hormone function.

FAQs

1. What is the Aldosterone Test used for?
This Test measures the level of aldosterone in the blood. Additionally, it helps diagnose adrenal gland disorders, investigate hormone-related high blood pressure, and evaluate electrolyte imbalances.

2. Do I need to prepare before the Aldosterone Test?
Yes. Certain medications, dietary salt intake, and body position can affect aldosterone levels. Therefore, your healthcare provider may provide specific instructions regarding medication use, diet, and sample collection before the test.

3. What does a high aldosterone level indicate?
A high aldosterone level may indicate primary aldosteronism (Conn's syndrome), secondary aldosteronism, or other adrenal gland disorders. However, the results should always be interpreted alongside plasma renin levels, your symptoms, medical history, and other diagnostic tests by a healthcare professional.
