Test includes: |
Adrenocorticotropic hormone. | |
Methodology: |
Electrochemiluminescence |
|
Synonyms: |
Adrenocorticotropic hormone, ACTH, CORTICOTROPIN, ADRENAL CORTICOTROPIN, CORTROSYN
|
|
Clinical significance: |
ACTH determinations are valuable in the differential diagnosis of adrenal insufficiency and hypersecretion. In primary adrenal insufficiency (Addison's disease), elevated levels of ACTH are typical, while low levels are the rule when adrenal insufficiency is secondary to pituitary dysfunction. ACTH may also be used to identify the cause of cortisol hypersecretion in Cushing's syndrome. | |
