Hi everyone, since my first post my private doctor started me on a trial of NDT for subclinical hypothyroidism.
Results 8/4/24 (before trial of NDT)
TSH 5.25 (0.27-4.2)
FT4 14.7 (12-22pmol/L)
FT3 3.2 (3.1-6.8pmol/L)
Started trial of NDT – ¼ grain x 2 daily
Repeat bloods 3/6/24 after 8 weeks on NDT (taken at 7am)
TSH 1.78 (0.27-4.2)
FT4 14.5 (12-22pmol/L)
FT3 4.4 (3.1-6.8pmol/L)
Doctor then increased NDT to half a grain x 2 daily. I have felt some improvement in symptoms but nothing drastic.
I have just had my next blood test results taken last week with the following results:
TSH 0.03 (0.27-4.2)
FT4 19.5 (12-22pmol/L)
FT3 9.0 (3.1-6.8pmol/L)
Obviously my FT3 is very high. Looking back I think i may have accidentally taken 0.5 grain before bed the night before the blood test (so 8 hours before).
Questions:
Would taking 0.5 grain 8 hours before the test be enough to raise my FT3 so much? (For context, I definitely do not feel like I have high T3 with ongoing hypo symptoms!). If this is true reading of what I'm like 8 hours after meds, is the number not too high?
If I take another test for more accurate results – when should I stop my meds if I currently take 0.5 grain on waking and 0.5 grain before bed?
The only two supplements I have added since before this last test were adrenal support and agnus castus and I can’t see that these products contain biotin to give a false high result unless anyone has any other information to say otherwise?
Really appreciate any advice you can give!
