I had blood tests on 26th of Feb. Unfortunately blood was taken 3 hours after I took 1/2 grain of ERFA.
Tests were done unexpectedly, in a hospital and frankly I did not have any energy to argue with blissfully ignorant doctor that taking NDT before Thyroid Function Test can skew the results.
Any way the results are as follow:
TSH 2.9 ref. range ( 0.3-5)
T4 14 ref. range ( 9-25)
T3 7.5 - ref. range (3.5-6.5) so at that point above the range.
At the time of above blood tests I was just on 3/4 gr of ERFA. I took my morning dose of 1/2 grain then approx. 3 hours later my blood was taken ( as mentioned above)
I feel dreadful and frankly beyond 'fed up'. I am on 1 grain of ERFA now, I have lowered the dose from 1 and a 1/4 of a grain after advice that I might have been increasing too fast.
My temperature do not jump up and down as much now ( still below normal), I have chest pains, fatigue, permanently sore throat and an incredible brain fog or rather a mental block, my memory is gone totally.
According to some hypothyroid sufferers particular kind of what's called a 'brain fog' can be caused not only by low T3 but also too much T3...
Does anybody know ( perhaps Rod?) how much ( approximately) the reading was influenced by NDT.
I am waiting for next tests results, and I pray that my surgery and lab perform tests that I have requested.
Thanks for help.

How can I have so many hypo symptoms when my TSH, T4 and T3 are all within 'normal' range!
T3 only blood results - help much appreciated
Shocked about T3 blood test results.
3rd blood test result (with ranges) on Levothyroxine, feel awful advice please.
Blood test results while on NDT
Edysia,
I would love to be able to answer your question usefully. This is my best guess - but it could be way out.
I would expect you to have been only slightly past the peak of both T3 and T4 blood levels. But we all know that individuals vary quite a lot. Typically blood levels peak somewhere around one to two hours after swallowing. Inevitably eating, drinking, chewing (or not), etc. all have their effects.
TSH should not be that far out because of the Erfa - but is likely to be significantly lower than it would have been at, say, 08:00.
Please folk, don't hold back in answering, or contradicting me. I would far rather someone did that than leave Edysia with only my answer.
All the best
Rod
Thank You so much Rod. I do appreciate your help. Perhaps if I was tested slightly after the peak than they are not skewed that badly. I was just curious if anybody came across similar situation.
E.
I agree with Rod in that I don't think TSH would be influenced too much (and it is still higher than you will probably need it to be anyway) but the T3 result probably was influenced significantly. What I have read in the past correlates with what you have said and it makes logical sense.
I wonder if there is an element of the T3 not getting into the cells or not being used by the cells at the moment (hence a high T3 reading), perhaps because they have been deprived for so long (I have no idea if I read this too, or just imagined it - brain foggy day). If this is the case, then a more gradual increase sounds like a good plan. This would also result in a more skewed blood T3 result.
