Aldosterone in Urine

Why It Is Done

An aldosterone test is done to:

• Measure the amount of aldosterone released into the body by the adrenal glands.
• Check for a tumour in the adrenal glands.
• Find the cause of high blood pressure or low potassium levels. This is done when overactive adrenal glands or an abnormal adrenal growth are suspected.
