Aldosterone Blood Test, LC-MS
The aldosterone blood test is used to evaluate patients with hypertension and for the possibility of hyperaldosteronism.
Description
The blood test for aldosterone (ALD) determines the amount of ALD present in your blood. Aldosterone is a hormone produced by the adrenal glands. The adrenal glands sit above the kidneys, and in addition to aldosterone, they generate several essential hormones. Too much aldosterone can cause high blood pressure and low potassium levels. When your body produces too much aldosterone, it is referred to as hyperaldosteronism. An adrenal tumor can cause primary hyperaldosteronism, which is usually benign or non-cancerous. Secondary hyperaldosteronism can also be caused by a variety of conditions, including:
- congestive heart failure
- toxemia from pregnancy
- cirrhosis
- low sodium
- some kidney diseases
- excess potassium
Aldosterone tests are often performed to diagnose fluid and electrolyte 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)
