Latest test results

[Lje05]

Following on from my last post on Wednesday I went to my surgery and requested a print out of my last blood test. I must have misheard the receptionist I spoke to on the phone as my TSH was 0.05 not 0.5.

Results were:

Serum TSH 0.05 mIU/L (0.4-5.0)

Serum free T4 17pmol/L (9-19)

I am seeing an endo in November and have made a GP appointment for the following day.

I am anticipating that the endo/GP will want me to reduce from 100mg of levothyroxine to 75mg.

I just wanted people's opinions or thoughts on these latest results and whether I should fight to stay on 100mg of levothyroxine or just accept that I go down to 75mg if that is what is suggested.

I have never had T3 tested so considering getting my T3 level tested.

Once again thank you everyone for all the advice

Lje05 How do you feel? If you feel well then don't accept a reduction in dose. You can't be overmedicated unless your FT3 is over range, so ask them to test that to prove you're overmedicated.

In support of this - from thyroiduk.org.uk/tuk/about_... > Treatment Options

" Dr Toft states in Pulse Magazine, "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)."

Dr Toft is past president of the British Thyroid Association and leading endocrinologist. You can obtain a copy of the article by emailing [e-mail] to show your GP and endo.

Thank you for the advice. I don't feel overmedicted. I've only been on 100mg of levothyroxine for two months but I feel much better than I did 2mths ago. I am still experiencing the sensation of a lump & tightness & tension in my throat plus low mood but neither of the above are as frequent or severe as they were. I'm no longer experiencing all the other symptoms I had before I was on 100mg
