The Aldosterone Upright test measures the levels of aldosterone hormone in the blood while the patient is in an upright position, typically standing. Aldosterone is a hormone produced by the adrenal glands that helps regulate blood pressure and electrolyte balance in the body. This test is usually performed to diagnose conditions related to aldosterone imbalance, such as primary aldosteronism (Conn's syndrome) or secondary aldosteronism.

How our test process works!
The Aldosterone (Upright) test measures the levels of aldosterone, a hormone produced by the adrenal glands, while the patient is in an upright position. Aldosterone helps regulate sodium and potassium levels and maintain blood pressure balance. This test is often used to evaluate conditions such as hyperaldosteronism or other disorders affecting electrolyte balance and blood pressure.
Risk Assessment
The test is commonly ordered for individuals experiencing:
- High blood pressure (Hypertension): Particularly if it is resistant to treatment or occurs at a young age.
- Low potassium levels (Hypokalemia): Even if not accompanied by symptoms.
- Suspected primary aldosteronism: Caused by conditions like aldosterone-producing adenoma or bilateral adrenal hyperplasia.
- Secondary aldosteronism: Due to conditions like congestive heart failure, cirrhosis, or kidney disease.
Normal Range
- Upright position:
- Adults: 4 to 31 ng/dL (nanograms per deciliter).
- Values may vary slightly depending on the lab and methodology used.
Interpretation of Results
- High Aldosterone Levels:
- Primary Hyperaldosteronism: Often caused by adrenal adenoma (Conn's syndrome) or adrenal hyperplasia.
- Secondary Hyperaldosteronism: Related to conditions causing reduced blood flow to the kidneys (e.g., renal artery stenosis).
- Low Aldosterone Levels:
- Adrenal insufficiency: Such as Addison's disease.
- Certain medications: E.g., ACE inhibitors, diuretics, or steroids.
Sample Type
- Sample Collected: Venous blood sample.
- Positioning: Blood is drawn after the patient has been upright (e.g., standing or sitting) for at least 2 hours.
