Adrenocorticotropic Hormone (ACTH) Plasma Test

ACTH, Adrenal Corticotropin, Corticotropin


Test Code: 004440
Specimen Type: Blood

Description:

Adrenocorticotropic Hormone (ACTH) Plasma Test

This test measures the level of Adrenocorticotropic Hormone (ACTH) in the blood.  ACTH is a hormone produced by the pituitary gland which stimulates the production of cortisol.  Cortisol is produced by the adrenal glands.  Conditions which affect the pituitary or adrenal glands can cause the balance between ACTH and cortisol production to be thrown off. 

This test is usually ordered to monitor or aid in the diagnosis of conditions which are associated with excessive or deficient cortisol levels.  These can include Cushing syndrome, Addison disease, hypopituitarism and ACTH-producing pituitary tumors.  ACTH testing is often ordered with a Cortisol Blood test.     

Turnaround time for this test is typically 1 business day.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Requirements:

Collection for the Adrenocorticotropic Hormone (ACTH), Plasma test should be done between 7 am and 10 am when ACTH levels are highest.

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample

Certain medications may affect the accuracy of this test.  It is advisable to consult your prescribing physician prior to having your blood drawn.

Requirements:

Collect specimen between 7 a.m. and 10 a.m.

With people receiving more than 5mg/day of biotin, a sample should be taken no sooner than eight hours after previous dose. People treated with monoclonal mouse antibodies may have inaccurate results. High titer of antibodies such as streptavidin and ruthenium may cause interference. Due to its correlation with cortisol levels, ACTH concentration is affected by stress. Any single measure may be within the reference range for people with increased production (Cushing's disease) or minimal production of ACTH.
