Hi - according to a recent TFT test my TSH level is 0.26 (range is 0.3 - 4.2) can someone please explain where is 0.26 within the range I've given as I don't understand how to read the figures. Thanks

Hi Adara13, your result is similar to mine - below the range used by the lab which tested your bloods. If you put a zero as the second decimal number in the range figures it makes it easier to see: 0.26 (0.30-4.20)

So the lowest it is expected to be, is 0.30, and you are measuring as 0.04 below that.

Some GPs will often see a TSH below the range as being evidence of over-treatment, and will want to reduce meds. Others have the view that to have achieved that is necessary for some people, to alleviate symptoms of under-treatment. So the key thing is, how do you feel on your present dosage? Do you feel more hyper than hypo, or do you feel okay? That is the acid test. :-)
