Can the Short Synacthen Test diagnose (SST) Secondary Adrenal Insufficiency?
The test entails administration of an ACTH bio-similar agent to stimulate the Adrenal Glands to produce Cortisol then blood tests are taken at 30 and 60 minutes post administration however surely this will only identify issues with Adrenal and not the ACTH producing cells in the Pituitary Gland - am I right in my understanding?
Plasma Bloods for ACTH are unhelpful as the health of these aforementioned glands can only be identified if the bods is under stress as essentially we are testing their response to stress.
I'm Hypopit and my SST confirmed I was low normal which suggests there is problems with my adrenals despite being within reference ranges so not 'clinically sufficient' however as I'm Hypopit, shouldn't my Endo have conducted an Insulin Tolerance Test to rule out Secondary Adrenal Insufficiency?
I would appreciate your comments.
