An aldosterone blood test measures the amount of aldosterone (ALD) in your blood. It’s also called a serum aldosterone test. Aldosterone is a hormone that is produced by the adrenal glands. The adrenal glands are positioned on top of the kidneys and are responsible for producing several essential hormones. Aldosterone affects blood pressure and also regulates sodium (salt) and potassium in your blood, among other functions.

Too much aldosterone can contribute to high blood pressure and low potassium levels. It’s known as hyperaldosteronism when your body makes too much Aldosterone. Primary hyperaldosteronism could be caused by an adrenal tumor (usually benign, or noncancerous). Meanwhile, secondary hyperaldosteronism could be caused by a variety of conditions. These include:

  • congestive heart failure
  • cirrhosis
  • some kidney diseases (e.g., nephrotic syndrome)
  • excess potassium
  • low sodium
  • toxemia from pregnancy

An aldosterone test is often used to diagnose fluid and electrolyte disorders. These may be caused by:

  • heart problems
  • kidney failure
  • diabetes insipidus
  • adrenal disease

The test can also help diagnose:

  • high blood pressure that is hard to control or occurs at a young age
  • orthostatic hypotension (low blood pressure caused by standing up)
  • overproduction of Aldosterone
  • adrenal insufficiency (underactive adrenal glands)
