Use
The Adrenocorticotropic Hormone (ACTH) Stimulation test is used to screen, diagnose, and monitor diseases associated with excess or deficient cortisol production, such as adrenal insufficiency and hypopituitarism. This test is particularly useful in evaluating adrenal function and can aid in the diagnosis of conditions related to abnormal cortisol levels.
Special Instructions
Collect a single timed specimen at 0 minutes. The specimen must be labeled with the time drawn. Follow proper collection and transport instructions to ensure valid results.
