1.0 ACTH with 238nmol/L cortisol? Does time of day really affect the outcome that much?
Hi all, I had a huge battery of pituitary endocrine blood tests done as I have an MRI that reported mass effect on my pituitary due to severely enlarged ventricles, I am not shunted
I haven't met with my endocrinologist yet since receiving all my results and among the numbers I got back I was wondering if 1.0pmol/L acth can ever be considered normal? I feel generally ok despite major fatigue and dizzy spells not really what I imagine adrenal insufficiency to cause. Especially since the cortisol was 238?
The draw was done at 3:15 pm so not sure if that would cause the drop, I do have a comparable from 2 years ago which was 8.9pmol/L and 528nmol/L cortisol
The ref range only considered numbers less than 10.2 to be normal so ofc this appeared as normal. Just not sure if that's the end of the story. I know I'm in good hands though
Any insight is appreciated 🙏🙏
