I have just had a blood test and managed - at last - to get my Free T3 tested! I would appreciate some help in interpreting the results. I have been on T3+T4 (Nature Throid) since December (after stopping Levothyroxine). I take sub-lingual B12 and a daily multivitamin. I stopped my Nature Throid 36 hours before my morning test (ie missed 3 doses).
B12 463 (180-2000 ng/L
Serum Folate 16 (2.8-20 ug/L
Ferritin 151 (20-300 ug/L)
TSH 0.04 (0.2-4.5 mU/L
Free T4 9 (9-21 pmol/L) It was 14 a year ago
Free T3 3.6 (2.6-6.2 pmol/L)
Vit D is listed 'to follow' but as previously been ok.
I suppose the thing I am most worried about is that the Free T4 reading has gone down so much - to what it was for years in fact - but maybe that is because I am now on Nature Throid rather than Levothyroxine. Any help would be appreciated.
