Swan, NHS Labs often decline to test FT3 unless TSH is suppressed <0.04. Your FT4 is 'ideal' but your TSH is probably a little high for comfort. That, and your low temperature are indicative of hypothyroidism but I don't think you will get a diagnosis until your TSH is >5.0.
My TSH a couple of weeks before the 2.7 reading was 3.1, but not sure what time the blood were taken, so whether they are comparable etc.
Not sure what to do now as I feel terrible and am stuck with brain fog, bowel problems and a host of other symptoms my GP does not seem concerned about or willing to act on.
I wonder if this article may help. There are other links on this website if you care to do some research. They have been supporting thyroid patients for many years.
