Other than the short SynACTHen, can anyone recommend any tests for secondary adrenal insufficiency? As a much removed pituitary patient and persistence of symptoms despite T3 (which has definitely helped but not cured) I'm beginning to think of it as a possible culprit. As all find, it takes a good 3 weeks to see your GP then another week for a blood test and another week or so to get results,and if it's budget able I'd like the infamous numbers sooner rather than later. I am tempted to up the T3 from its current 25(10+10+5)but that does seem a reasonable dose...any more could so easily send me hyper especially with the adrenals possibility. Has anyone any thoughts?
