*** edited to add FT3 was 3.20. (Range 2.30-4.20).
Doctor did bloods for another issue but TSH & T4 were on there.
TSH 0.06 (range 0.55-4.78), so I know being on NDT this low is fine
FT4 0.31 (range 0.89-1.76) so am way below range and believe it should be mid range.
I take NDT(S-Thyroid) x 1 per day and T3 x 1 per day.
Why would my T4 be running so low, what can I do to get it up? Both are flagged on my results for when I go back next week so will have to explain what I am taking.
