Re: ACTH Stim test while on Florinef
I wasn't taking fludro when I had my two ACTH stim tests, but had to stop the last hydrocortisone tab the day before and not take the morning one on the day of the test. Once the test was done I could take the hydrocortisone. For the second test they even told me not to take my asthma inhaler in the morning! So I wouldn't be surprised if they would want you to just miss the morning Florinef and take it once the test is done, but the safest thing is to ring them as you don't want to stop a tablet that you need or take it and invalidate the test. I had to ring my hospital a week before the test to discuss my meds etc and they told me what to do then.
Good luck with your test,
