I got the following results back today:
Total thyroxine - 73.2 (58-154nmol/L)
TSH - 0.139 (0.4-4.0)
FT4 - 15.3 (10-22)
FT3 - 2.72 (2.8-6.5)
FT4:FT3 ratio - 5.6 (2.0-4.5)
Thyroglobulin - <20 (0-40)
TPO - 74.6 (0-35)
I am confused! I am taking 75mcg and have been since September. In Nov TSH was 0.75 and I was feeling well, mid-Feb it was 1.3 and I still felt pretty good, and now it's 0.139 which is the lowest it's ever been - yet I am having hypo symptoms, not hyper. This is the first time I've had a full profile done (at the request of my naturopath) so I don't have anything to compare with.
Any thoughts on low TSH and low FT3, and what I should do about it, would be very much appreciated. My naturopath is getting some supplements for me which support FT4 to FT3 conversion, has anyone had success with similar? Should I go back to the doctor?
Many thanks in advance,
