I wrote to endo asking for short synacthen test following advice given here. (blood test showed morning cortisol off the nhs scale) He wrote back and suggested a long synacthen test.
What does this mean and is it better? It will involve a whole day off work with tests throughout the day and then returning the next morning for another.
I feel v unwell with even small amounts of blood taken so need to know it’s going to be worth the hassle.
He said it’s better than the short test and it will show adrenal reserve and insufficiency
Also, he never suggested the ACTH (I think that’s what it’s called?)
Should I write back and ask for that also?
