synacthen test

Posted , 4 users are following.

I had this test, results were baseline cortisol 508nmol/L. Cortisol at 30 mins 690nnol/L and 60 mins 782nmol/L. I had the synacthen IV, but not sure of the dose.

Felt stressed before the test as it took 30mns and 3 attempts to put the line in.

    Yes, I felt stress as well because it was getting well pass the 'early hour' for checking the cortisol. If you are not sure of the dose.... I cannot check or imagine what the results are...

    If you ask the UK Addison's disease Association, they will probably ask you the dose...

    First of all, the dose of synacthen* is not critical so long as it is enough - it is an on/off trigger. It is 'just' a copy of the signal hormone that your pituitary would send to your adrenal glands to order up some cortisol, which they produce in response to physiological stress - inflamation, injury and the like. (A one-off psycological stress caused by having the test done [even awkardly] won't affect the result. The object of the test it to confirm (or deny) that your adrenals are responding to orders from the pituitary (which sends this kind of signal hormone to many major hormone-producing organs) to produce cortisol when needed.

    Your baseline cortisol is well within the normal limits and the response from your adrenals looks to my amateur eye to be spot on.
