He's not convinced as I'm only just under the reference range and he's checked some of my other pituitary hormones and they are normal. He thinks having a FT4 of 11 may just be normal for me. This is why he's doing the test as he won't medicate me if it comes
back normal.
I see your FT4 is a lot lower than mine, so presumably that's why they didn't need to do one on you?
I'm not looking forward to it as I hate needles and there are drips/injections and multiple blood draws. Eek. But at least hopefully I will get an answer.
Did you find out which type of central you had and why your TSH wasn't higher? Did you have an MRI?
Apparently I'm tertiary ( hypothalamus). I did have a pituitary scan which showed a wonky shaped pituitary gland with a domed surface. There was no adenoma though. My pituitary hormones are normal so I believe but what does 'normal' mean!
In order to get my FT4 and FT3 high enough my TSH is incredibly low.
