Question

What tests are done to check adrenal function?

Answer 1

Adrenal gland:

1. Adrenal glands are tiny, triangular-shaped glands found on top of both kidneys.
2. Adrenal glands create hormones that aid in the regulation of metabolism, the immune system, blood pressure, stress response, and other vital processes.

Parts of the adrenal gland:

1. The adrenal glands are divided into two parts: the cortex and the medulla.
2. The cortex is the gland's outer layer. It is responsible for the production of the hormones cortisol and aldosterone.
3. Meanwhile, the medulla is the gland's innermost layer. It is responsible for the production of the hormones adrenaline and noradrenaline.
4. The adrenal glands can be affected by a variety of medical disorders.
5. These include Addison's disease, Cushing's syndrome, and adrenal cancer, as well as high blood pressure caused by aldosterone overproduction.

Test for checking adrenal function:

1. A person's urine or blood sample can help in evaluating the number of adrenal hormones and diagnosing a functioning tumour, such as the ACTH stimulation test, Insulin tolerance test, CRH stimulation test, and so on.
2. A CT or CAT scan (computed tomography) or an MRI (magnetic resonance imaging) scan can assist to detect an adrenal gland tumour and establish whether or not it is malignant.
