I remember reading on here ages ago that the acceptable levels of thyroxine etc in the UK were judged differently from other countries, and consequently a lot of people with issues were being overlooked.
Mine are currently TSH 1.34 and FT4 13.9. They are apparently on the low side of optimal, but still ok.
Could anyone with any experience of this kind of thing shed light? Thyroid issues run in my family and I'd be interested to see if these results would be seen differently under different criteria
