As lots of you will know I have been posting on here regarding 'normal' TSH levels and low Free T4. I have now had two sets of blood results taken in Nov that demonstrate low Free T4 levels (0.1 below the ranges given).
After 2 days of chasing my endo who hadn't even looked at bloods I had taken with her (on the 27th Nov) she has looked at them and come back to me saying everything is 'normal'. I asked for my Free T4 level on this set of bloods. She told me that my Free T4 was 9.7 and the range starts at 7.5 so nothing there that indicates I need any medication regardless of the fact that my other two sets of results were 0.1 lower than the range.
I had my Medichecks bloods done on exactly the same day as endo bloods. Results:
Medichecks
Free T4 11.9 Range 12-22
Endo Bloods
Free T4 9.7 Range 7.5 plus
Why is it that on one set of bloods my results are low and the other are 'normal' according to endo when they were taken on the same day?
My GP Free T4 result taken a couple of weeks before was 7.8 Range - 7.9 - 16.
I'm totally confused now as the endo said none of my problems are thyroid related (even though I questioned why I had already had 2 tests that month which show Low Free T4 results).
It was only a phone conversation as they are refusing to give me the results on paper. She said to have cortisol tests done now - not sure what that will reveal. Any ideas?
I have my GP tomorrow and now worried that the endo has a set of results that will contradict all the others I've had and they will refuse to treat anything.
Sorry to keep asking so many questions but I feel totally baffled now!

You mentioned central the other day when you posted thank you.
The endo gave me no idea of any of the other results and just said there isn't a thyroid issue at all. I questioned this and all she said was that she will now test my cortisol.
I've asked the private hospital for my results and they said it is against protocol to give me my results.
I'll ask the GP for them instead when I go tomorrow. TSH is always within the ranges given.
Medichecks did my Free T3 that was within the range but they couldn't do my T3 and are sending a repeat test to me.
The Data Protection Act entitles you to your test results and trumps the private hospital's protocols. If you can't get the results from your GP email the hospital with a subject access request for your results and ranges. ico.org.uk/for_the_public/t...
Its clear that you have had FT4 tests done with greatly differing methods. The one showing a lower limit of 7.5 is pretty questionable as to its validity. This might come from its design or it might be that the method used to get the healthy range was dodgy. I would rely on the Medichecks test which does have an acceptable lower and upper limit and range.
Because there has been inadequate control of the quality (QC) of tests by the relevant authorities. There is a QC system across the UK, and to my knowledege it has been useless in pressing for proper calibration of tests. This problem is being addressed but, my goodness, it does take a long time.
Yes Medichecks gave me all the results but their doctor summary said I was unlikely to have a thyroid problem even though the Free T4 was * asterisked as it was lower than their starting range!
All very new to me but I am learning. I guess I've always thought GPs judgement should be trusted so if they say everything is 'normal' I wouldn't normally question it. I can see that with thyroid it's a slightly different story!
