What is an adrenocorticotropic hormone (ACTH) test? This test measures the level of adrenocorticotropic hormone (ACTH) in the blood. ACTH is a hormone made by the pituitary gland, a small gland at the base of the brain. ACTH controls the production of another hormone called cortisol.

What tube is cortisol drawn in?

What is a EDTA tube?

It’s a tube coated with spray-dried K2EDTA on its inner wall. EDTA acts as an anticoagulant, binding the calcium ions and interrupting the clotting of the blood sample. EDTA is used for most hematology procedures, assessing complete blood count, preparing EDTA plasma, whole blood collection and bone marrow specimens.

What happens if your ACTH is high?

What Problem Can Occur With ACTH? If too much ACTH is produced, this can lead to high levels of cortisol in the body, also known as Cushing syndrome. The most common cause of increased ACTH production is a benign pituitary tumor. When this is present, the disorder is called Cushing disease.

What labs check pituitary function?

Blood, saliva, and urine tests can be used to detect high levels of cortisol. Additionally, a doctor can measure blood levels of ACTH. High levels of thyroid-stimulating hormone, or TSH, in the blood, which can cause hyperthyroidism, may, rarely, indicate a pituitary tumor.

How is the ACTH test performed?

Your blood is drawn. You then receive a shot (injection) of ACTH, usually into the muscle in your shoulder. The ACTH may be a man-made (synthetic) form. After either 30 minutes or 60 minutes, or both, depending on how much ACTH you receive, your blood is drawn again.

What is the normal range of ACTH?

7.2−63.3 pg/mL ( Note: For samples collected between 7 AM and 10 AM) Adrenocorticotropic hormone (ACTH), or corticotropin, is a peptide hormone consisting of 39 amino acids. It is produced in the anterior pituitary of the brain as part of the precursor molecule pro-opiomelanocortin (POMC).
