Is used to determine if the adrenal glands are producing enough aldosterone. Improper levels may indicate an endocrine disorder known as Conn Syndrome.

Aldosterone is produced by the adrenal glands, which helps regulate numerous areas of bodily function. It is essential in the process of electrolyte balance, blood pressure and blood volume. Excess levels of aldosterone may indicate an adrenal tumor, benign, non-cancerous. This is known as primary aldosteronism.

Secondary aldosteronism is far more common than primary and may be caused by anything that results in increased levels outside of an adrenal gland disorder. Dehydration is one of the more common causes. Other causes of secondary aldosteronism may include congestive heart failure, cirrhosis, kidney disease or other unknown causes.

Low levels of aldosterone may indicate adrenal insufficiency. This condition may lead to low blood pressure, low sodium levels and possible high levels of potassium. It can often cause dehydration.
