Addison's Disease Test, Cosyntropin Stimulation
6 days
Electrochemiluminescence immunoassay (ECLIA)
Draw blood for baseline cortisol. Inject cosyntropin 250 μg IM or IV (if IV, dilute cosyntropin in 2-5 mL of sterile saline and inject over two minutes). Draw blood for stimulated cortisol 60 minutes after. Treatment for patients in suspected adrenal crisis should not be delayed while waiting for the results of ACTH (cosyntropin) stimulation testing. Formal confirmation of diagnosis can be carried out after clinical recovery.
