If you have Fibromyalgia/ CF symptoms and have a blood test for T3 could the test result still come back showing as normal even though you are not feeling normal. (same as other bloods that don't give the true/correct readings) ?
Does a T3 blood test give a true reading or not ? - Thyroid UK
Does a T3 blood test give a true reading or not ?
By 'normal' do you mean it was within range? A lot of people feel pretty bad if it is low in the range. Do you have your results or have they just told you it's normal?
...I think you know there is no such thing as normal In range it may be but that is not good enough. FT3 needs to be at least in the upper third of the range. I have seen loads of blood test results here in Crete - some on thyroid medication and some not - everyone seems to have LOW T3. There is certainly something going on with conversion of T4 into the T3 When we learn from this forum how important Iron folate B12 Ferritin & VitD are and we know most people are not near the TOP of the ranges it does make you think....diet has to be important here.
Often read about Low T3 syndrome too - perhaps it's on its way into mainstream medicine. Really need to see all the results to understand the bigger picture. Anti-bodies ? were they tested - results ?
One important thing to remember is that the blood test is a snapshot - and also the FT3 test can show an inaccuracy of up to 50% I believe - either way. So it is important to consider it along with the other results....
More info please Coastwalker .....

Hi Marz
Can you tell me please if there are any research papers that say that T3 should be in top quarter of range.Thanks Jill
Am sure someone will come along and tell you where to find research papers. I have just learnt from this forum that time and time again people say FT3 needs to be towards the top of the range....the upper third. Type FT3 blood test results into the Search box on the Green Bar above and see what comes up....it's bedtime here in Crete - will have a scout around in the morning and see what I come up with.....
Thank Q Marz. X I'm going to start making some 'at a glance' charts up as there is so much to remember, you always think you will remember it, but if you don't use it you loose it, same goes for writing it down on paper, I have so much bits of paper hanging around with important bits of thyroid info on, but try locating that important piece and it's gone
