Sunday, I'm not "fixated on rT3" anymore than I am "fixated" on any other thyroid result. The entire and complete thyroid panel needs to be done if you are starting out and diagnosing something. It doesn't need to be done every time, once things are stable.
As for "you've also been given very similar information as to rT3 being a red herring...." - sorry, that's just rude. You can give me all kinds of 'information', but the last time I checked there was freedom for us to decide which information to adopt and which not to. When there are multiple reputable doctors clearly stating that rt3 is an essential test, I'm not sure why you think I should believe the "information" people have given me here, over that? (BTW Crispy, look up the podcast called 'The Thyroid Fixer' by Dr Amie Hornaman. She also has a FB group you can join. You can also check out Dr Childs, including his many YouTube free videos on rT3 and thyroid stuff too. I was first prescribed T3 on the basis of my high rT3 result by Dr Conway at The Thyroid Clinic, which is an online clinic you can google. And I now see Dr Momi at Functional Thyroid Care - who I recommend more.)
I am not trying to "pick holes" in everything you say, Sunday, I am disagreeing with you. I'm sorry that's difficult for you, but I simply don't agree with some of the points you make.
"Yes, TSH should not be relied on as a monitoring tool in people with thyroid disease but is useful as a tool during diagnosis." Like everything else in a COMPLETE thyroid panel, TSH is just part of the picture. As you can see from my own set of results above with normal TSH and far below normal thyroid hormones.
Crispy, looking at your results, they are very unexceptional (in a good way) and are not really 'low' for someone not on thyroid medication. How to interpret a thyroid panel differs when someone is on meds and not on meds. Most people on meds need their T3 to be almost at the top of range to feel okay, for eg. That isn't the case for people not on medication. As said many times, there is nothing you can ask your NHS GP for. It is not up to him/her whether to test you or not, they are simply *not allowed* by the lab/NHS to order the relevant tests. Only consultants/endos can order those other tests. The only way you will get a complete thyroid panel is if you pay for it.
