It's not possible to read your result, it's the wrong way round and it's blurred.

There seems to be only 2 results there, why not just type them it, it's probably quicker than taking a photo and uploading it. Please include the reference ranges and then members can comment.

I will delete your other post which had no information included.

Ok thanks its serum TSH level says below range 0.01 mu/L (0.27-4.2)Serum freeT4 level says above range (25.2 pmol/L(12.0-22.0) thats all there was.

TSH: 0.01 (0.27-4.2)

FT4: 25.2 (12-22)

So yes, it's understandable why you've been told you're overmedicated as your TSH is classed as suppressed with an over range FT4.

However, as Greygoose pointed out in your previous thread, you need FT3 tested and that tells us if we are overmedicated if that is above range. I would talk to your GP and ask that FT3 be tested along with TSH and FT4. The labs tend to overrule GPs request for testing FT3 but if it's not tested you wont know. Use the following information to show your GP why FT3 needs to be tested:

Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine (the magazine for doctors):

"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l. In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l. This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l).*"

*He recently confirmed, during a public meeting, that this applies to Free T3 as well as Total T3.

You can obtain a copy of the article by emailing Dionne at

tukadmin@thyroiduk.org

print it and highlight question 6 to show your doctor.

Chances are that your FT3 is not in balance with your FT4 which would probably indicate poor conversion of T4 to T3.

Thanks for that info Seaside Susie, I did ask for extra tests but they saud next time, so poor conversion is down to vits? Or something else.

You may not get FT3 done, as explained.

so poor conversion is down to vits? Or something else.

No, not just down to vitamins but it helps if they are optimal. Some of us convert well, some of us don't. We can have optimal vitamin levels and still have poor conversion.
