Description: Aldosterone and Renin tests evaluate whether the adrenal glands are producing enough amounts of aldosterone and to differentiate between the likely causes of excess or deficiency.

Both aldosterone and renin levels are highest in the morning and vary throughout the day. They are affected by the body's position, by stress, and by a variety of prescribed medications.
