This test evaluates cortisol production and adrenal function to help screen for abnormal hormone patterns that may be associated with symptoms such as unexplained weight gain, fatigue, mood changes, or elevated blood pressure. It may be used to support the clinical investigation of conditions like Cushing’s syndrome or Cushing’s disease.

Included Tests:

• Low-Dose Dexamethasone Suppression Test (DST):
  Assesses whether your body properly suppresses cortisol production in response to a synthetic steroid. Failure to suppress may indicate excessive cortisol levels.

• ACTH Blood Test:
  Measures levels of ACTH (adrenocorticotropic hormone) to help determine whether the source of excess cortisol is from the pituitary gland (Cushing’s disease) or another area, like the adrenal glands.

What It’s For:

To assess cortisol levels and rhythm throughout the day and identify possible imbalances in adrenal hormone output.

Benefit of the Test:

Offers valuable insights into how your adrenal glands are functioning, helping your provider investigate whether further testing or treatment is needed for cortisol-related conditions.
