Test Code ACTH ACTH (Adrenocorticotropic Hormone)

Important Note

Test must be drawn in pre-chilled EDTA tube. Transport on ice.

Performing Laboratory

Hunterdon Medical Center Laboratory

Useful For

Adrenocorticotropic hormone (ACTH) stimulates the formation and secretion of glucocorticoids (cortisol) by the adrenal cortex. Plasma measurements of ACTH are useful in the diagnosis of syndromes assoiated with hypercortisolism and hypocortisolism.

  • Collect specimen in a pre-chilled EDTA tube.
  • Centrifuge specimen and separate plasma within 3 hours.
  • Freeze separated plasma if not delivered to the laboratory within 3 hours.

Day(s) Test Set up

Monday through Sunday

Reference Values

7.2-63.3 pg/mL

  • ACTH Reference values are valid for AM collections.
  • There are no established reference values for PM draws.
    Note: ACTH concentrations vary depending on physiological conditions. Therefore, ACTH results should always be evaluated with simultaneously measured cortisol concentrations.
