Water Retention Panel: Renin Activity and Aldosterone

Renin Activity and Aldosterone

Renin is also called angiotensinogenase; it’s an enzyme produced by the kidneys to control aldosterone production. It’s also essential in the renin–angiotensin aldosterone system (RAAS) which maintains your body’s fluid balance and blood pressure. Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Aldosterone tends to promote Na+ and water retention, and lower plasma K+ concentration.
