An aldosterone test measures the amount of the hormone aldosterone in blood.
|
|
This test measures the levels of aldosterone, a hormone produced by the outer part (cortex) of the two adrenal glands, organs which sit one on top of each of the kidneys. Aldosterone regulates the amounts of sodium and potassium in the blood. This...

|
The 24-hour urinary aldosterone excretion rate test measures the amount of aldosterone removed in the urine in a day. Aldosterone is a hormone released by the adrenal gland that helps the kidney control salt and potassium balance. See also: Blood ...

A computed tomography (CT) scan is an imaging method that uses x-rays to create cross-sectional pictures of the body. See also: Cranial CT scan; Lumbosacral spine CT scan; Orbit CT scan; Thoracic CT scan.
|
|
|
Computed tomography (CT), formerly referred to as computerized axial tomography (CAT), is a common diagnostic imaging procedure that uses x rays to generate images (slices) of the anatomy.
|
|
|
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross-sectional views of body organs and tissues.

|
|
Computed tomography (CT) scanning is a valuable diagnostic tool that provides physicians with views of internal body structures. During a CT scan, multiple x rays are passed through the body, producing cross-sectional images, or "slices, " on a ca...

Adrenocorticotropic hormone test (also known as an ACTH test or a corticotropin test) measures pituitary gland function.
|
|
This test is a measure of serum cortisol (also known as hydrocortisone), or urine cortisol (also known as urinary free cortisol), an important hormone produced by a pair of endocrine glands called the adrenal glands.
|
|
ACTH (cosyntropin) stimulation test measures how well the adrenal glands respond to the hormone ACTH. ACTH is a hormone produced in the pituitary gland that stimulates the adrenal glands to release cortisol.
|
