Hello everyone, i have been on NDT since April. I have two sets of blood results to run by you, taken at the end of June when on 2.5 grains of Thiroyd a day, and earlier this week having been on 2.25 grains since July 1st. On both occasions TSH was 0.03.
June: FT3 8.2 (2.8 - 7.1) FT4 14 (10 - 23)
Oct: FT3 5.9 (3.1 - 6.8) FT4 11 (12 - 22) I assume they have changed the ref ranges or lab between times.
I wonder if the T3 is 'pooling' to produce these numbers? I understand that this can be affected by iron levels, which were tested in June and here are the results:
TIBC 52 (45 - 81),
Transferrin % saturation 33 (15 - 45),
Serum iron 17 (6.6 - 30.4),
Serum Transferrin 2.3 (2 - 3.6),
Serum Ferritin 63 (not 67 as said earlier),
Haemoglobin 12.3 (low 12.5),
Haematocrit 0.35 (low 0.37).
GP did not repeat these tests this time. Also cortisol: last time it was checked (saliva test in April), my cortisol was too high and i take zinc and Holy Basil for this.
Or is it perhaps because i need to change to T4 only - Levo - and add in a lower dose of NDT for some extra T3? I understand there are sometimes problems with there being too much T3 in NDT for those who convert well.
In Aug 2015 I had raised Antithyroglobulin, and TPO in range - antibodies have not been checked since. My thyroid apparently is (otherwise) fine (according to the endo) no nodules etc
Thank you for any advice
