Adrenocorticotropic Hormone (ACTH) Blood Test

Item # LC004440

Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland, which controls the production of cortisol. This blood analysis of ACTH aids in the evaluation of the pituitary gland and disorders characterized by abnormal cortisol levels.

Adrenocorticotropic Hormone, also known as ACTH, is a test for pituitary function and is useful in evaluating conditions associated with excessive or deficient cortisol production in your body.

Signs that you may have too much cortisol include:

  • Central Obesity
  • Rounded Face
  • Sexual dysfunction (especially in men)
  • Thin skin which bruises easily
  • Depression
  • High glucose levels and high blood pressure

Signs that you may have insufficient cortisol production include:

  • Fatigue
  • Nausea and decreased appetite
  • Increased skin pigmentation
  • Weakness
  • Craving for salt

Normally, ACTH will be at its highest level in the morning and lowest at night. Upon waking, ACTH stimulates the production of cortisol and both show a diurnal variation. Conditions that affect the production of ACTH and cortisol often disrupt this variation, which is why it is important to evaluate them together.


Fasting is not required for this test. Take all medications as prescribed. ACTH should be drawn between 7-10 AM.
