The aldosterone (ALD) blood test measures the amount of ALD in your blood. Aldosterone is a hormone made by the adrenal glands. The adrenal glands are located above the kidneys and produce several essential hormones.

Too much aldosterone can lead to high blood pressure and low levels of potassium. When your body makes too much aldosterone, it is known as hyperaldosteronism. Primary hyperaldosteronism may be triggered by an adrenal tumor which is usually benign or non-cancerous. Additionally, a variety of conditions can cause secondary hyperaldosteronism including:

  • congestive heart failure
  • toxemia from pregnancy
  • cirrhosis
  • low sodium
  • some kidney diseases
  • excess potassium

Aldosterone tests are often performed to diagnose fluids and electrolytes disorders. These disorders could be caused by:

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

This test is commonly used to help diagnose:

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