Hi
Does anyone here have Hyperparathyroidism (PHPT) and has found that their TFTs are suddenly weird?
A usual result for me is TSH anywhere between 0.7 and 2.5 (0.3 to 5), a fT3 of 3.1, range (3 - 6.9) (poor converter) and a fT4 of 18.5 (12-22).
The previous 2 tests I had done, both times they did not give me a fT4 result. Once was a ruined sample, the other was just ignored. TSH was done both times though and was approx TSH 0.7ish, fT3 of 4.1. Apparently, I can suddenly convert?!
So I finally got a fT4 this week after a third time of them saying the sample was unusable. Had it redone and the results were TSH 0.42, fT3 4.2 and fT4 of 27.7! My GP considers this normal and no further action needed.
I've tried various other ways of dealing with my hypo over the years, including NDT and T4/T3 combo. When I am on 100mcg of Levo though my fT4 is always about 18.
I had an ultrasound scan and then a sestamibi scan that confirmed I had a parathyroid adenoma on the bottom right. My thyroid has been atrophied on the left since at least 2015.
Any ideas what might be going on?
