How do I prepare for an ACTH test?
You may be asked to fast for 6 hours before the test.
Sometimes, no special preparation is needed.
You may be asked to temporarily stop taking medicines, such as hydrocortisone, which can interfere with the cortisol blood test..
Why would ACTH be high?
High levels of ACTH may be caused by: Emotional or physical stress (such as recent surgery or severe pain). Diseases such as Addison’s disease (failure of the adrenal glands), Cushing’s disease (a tumor of the pituitary gland), or a tumor outside the pituitary (such as in the lung).
What does an ACTH stimulation test feel like?
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing. Why the test is performed: This test is helpful in determining if the adrenal and pituitary glands are normal.
What is the ACTH stimulation test used for?
The ACTH stimulation test may be used to investigate a low cortisol test result. It may be used to help diagnose primary adrenal insufficiency (Addison disease) if your healthcare practitioner suspects that your adrenal glands may not be producing enough cortisol.
What happens when ACTH is high?
An increased ACTH result can mean that a person has Cushing disease, Addison disease, overactive, tumor-forming endocrine glands (multiple endocrine neoplasia), or ectopic ACTH-producing tumors. A decreased ACTH result can be due to an adrenal tumor, steroid medication, or hypopituitarism.
What triggers ACTH?
Hypothalamic-Pituitary Axis Corticotropin-releasing hormone (CRH) is released from the hypothalamus which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.
Does anxiety cause high cortisol?
Cortisol is released in response to fear or stress by the adrenal glands as part of the fight-or-flight mechanism. This causes heightened levels of breathing and an increased heart rate. These short-term bursts of cortisol are necessary to help us recover from the effects of stress.

How do you interpret ACTH stimulation results?
Interpretation: A rise from the baseline of at least 7 μg/dL to 10 μg/dL of cortisol, reaching at least 18 μg/dL at 60 minutes post stimulation effectively rules out primary adrenal insufficiency and suggests that adrenal suppression is minimal.
What does a cortisol blood test check for?
A cortisol test is used to help diagnose disorders of the adrenal gland. These include Cushing’s syndrome, a condition that causes your body to make too much cortisol, and Addison disease, a condition in which your body doesn’t make enough cortisol.
What tests are done for adrenal function?
Blood and urine tests help measure the amount of adrenal hormones, which can detect a functional tumor. A computed tomography (CT or CAT) scan or a magnetic resonance imaging (MRI) scan may be useful in diagnosing an adrenal gland tumor and determining whether it is cancerous.
Do you need to fast for ACTH stimulation test?
You will likely need to fast for eight hours before the test. Your provider might advise you to stop taking certain medications for 24 hours prior to testing.
How do you test for ACTH deficiency?
The ACTH stimulation test is the test used most often to diagnose adrenal insufficiency. In this test, a health care professional will give you an intravenous (IV) injection of man-made ACTH, which is just like the ACTH your body makes.
