You are right - it is the aim of a treated thyroid patient to have a TSH of 1 or under. I will tag SeasideSusie from Admin who will give you the required info for your Endo. ☺

Dr Toft article 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 Dionne at tukadmin@thyroiduk.org print it and highlight question 6 to show your doctor.
