Are the results ok with a tsh that low? I did the test the way it’s supposed to be done. Thank you
Welcome aboard, yes your results look pretty good, more important how are you feeling?
Free T4 (fT4) 20.9 pmol/L (12 - 22) 89.0%
Free T3 (fT3) 5.4 pmol/L (3.1 - 6.8) 62.2%
T4:T3 Ratio 3.870
What are you taking at the moment and have you checked your ferritin, folate, B12 and Vit D levels which are all best optimized
Thank you for your reply.
I haven’t yet had my vitamins checked , I’ll do that. I feel unwell but my doctor said these results are fine. To begin with on 112 I felt ok , really needed the increase from 100. But over 6 months I’ve gone past feeling well to being absolutely exhausted all the time? I can’t exercise, I struggle to wake up, my appetite is much bigger than usual. Just not feeling great at all but doctor says all ok?
welcome to the forum
Is your hypothyroidism autoimmune
Do you always get same brand Levo at each prescription
What vitamin supplements are you taking
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Is this how you did this test
Next step
Test thyroid antibodies if not been tested
Plus vitamin D, folate, B12 and ferritin
Thanks, yes to all of the questions and I do always get the same brand. I was fine for a while it seems strange that I’m symptomatic again. I’ll get those vitamins done although they’ve been low in previous years and I felt tired but this is a lot different to that. This is can’t function properly at the minute
If that’s my highest tsh , is that a concern ? Seems very very low
Low vitamin levels result in poor conversion of Ft4 (levothyroxine) to Ft3
Low Ft3 results in even lower vitamin levels
Vicious circle downwards
High Ft4 tends to result in low TSH regardless of how poor Ft3 is
Essential to test and maintain OPTIMAL vitamin levels
Vitamin D at least over 80nmol
Serum B12 over 500
Active B12 at least over 70
Folate towards top of range
Ferritin at least over 70
If/once vitamin levels optimal if Ft3 remains low then look at getting SMALL dose T3 prescribed alongside levothyroxine
This has to be initially prescribed via endocrinologist
Here’s link for how to request Thyroid U.K.list of private Doctors emailed to you, but within the email a link to download list of recommended thyroid specialist endocrinologists who will prescribe T3
Ideally choose an endocrinologist to see privately initially and who also does NHS consultations so that might eventually transfer to getting T3 on NHS

I’m grateful for your response but I don’t have low t3 or high t4, do I ? I didn’t think I did but please tell me if I’m reading it wrong
Thanks for the vitamin ranges that’s really useful
Your Ft4 is perhaps/possibly a bit high at 89% though range
And the Ft3 is lower at 62%
That’s a reasonable difference in % through range
This might mean your vitamin levels are low
Or if vitamin levels are good …..perhaps taking slightly too much Levo
Before considering reducing levothyroxine a tiny amount you would want to check vitamin levels
Low vitamin levels, especially low ferritin or B12 could make you feel tired
But being over medicated could also make you feel tired
