Aldosterone is a salt-water metabolic corticoid secreted by the adrenal cortex that regulates blood pressure. Aldosterone blood test is important in diagnosing many diseases related to the liver and kidneys.

Aldosterone hormone is one of the hormones produced in the adrenal glands, maintaining the concentration of sodium and potassium in the blood at normal levels to create a balance in blood volume as well as arterial blood pressure. Therefore, measuring the concentration of aldosterone in the blood as well as urine is extremely necessary, helping to monitor and detect some abnormal pathological conditions.
