Around 10 years ago I had TSH (fairly low - around 1.5 I think) and T4 (12 - just above borderline), so wasn't followed up on, then around 6 years ago with New GP surgery it was written in my notes that I should have TSH, T4 AND T3. When the results came back there was TSH only (at 2.5). Finally a year later I managed to get an appt with an endocrinologist and they only did TSH (at 3) and T4 (at 11 - borderline again). When I asked the consultant why there was no T3, he told me that it was not required and to go away and live with it. The "IT" he referred to was fibromyalgia, a neuro condition which causes a lot of problems but has similar symptoms to low thyroid.
I am under the impression that when presented with symptoms of hypothyroidism, all 3 test should be done (regardless of what the differential diagnosis might be). Would that be correct??
Is there anything I can do to convince the GP that I can be retested now. Even though my symptoms are now a lot worse and clearly match up to hypothyroidism I feel they may not take it seriously and fob me off again. I have dowbted the fibro for a while as I have looked at my medical notes and seen references to psoriatic arthritis as well, which I don't recall (I had a few weird years in my 20s and 30s where I moved so much and lost a lot of my records, and got really mix up), so that is another thing I want to readdress.
