The Aldosterone blood test from Walk-In Lab helps evaluate patients with hypertension and for the possibility of hyperaldosteronism.Walk-In Lab’s Aldosterone blood test does not require fasting and results are delivered to the patient within two to three days. It is a cheap blood-test alternative for those patients without insurance or a doctor’s order.Aldosterone is vital in the control of blood pressure and blood volume. It is a hormone and mineral (sodium)-retaining steroid that directly regulates the kidney’s ability to retain salt. Additionally, aldosterone indirectly regulates the excretion of potassium. This hormone is produced by the adrenal cortex (the outer portion of the two adrenal glands located at the top of each kidney). In the majority of patients, measuring both renin and Aldosterone (and sometimes cortisol) is necessary in order to obtain a complete picture of what is happening with hormone production. These tests may be ordered to help diagnose and monitor a variety of conditions associated with Aldosterone deficiency or excess.
