Yet another blood test

Was self medicating with T3 on top of my T4 and had to own up to the GP when my annual bloods came back 'abnormal'. She convinced me to stop the T3 with a promise they'd consider reviewing the T4 following abnormal reading.

So just got it back and TSH is at 1.41 (0.34-5.6) and I've been's normal so that's that. So frustrated so looks like it's going to have to be self medicating either with more T4 or adding T3 back :(

What was the abnormal reading?


TSH was completely suppressed apparently haven't been able to get my hands in that yet



Suppressed TSH does not mean you are over medicated as long as FT3 is within range. If your GP will only test TSH you can order private thyroid tests via Blue Horizon Thyroid Plus 6 will test TSH, FT4 and FT3.


Yep had done that previously to try and get to the bottom of it


The problem is that because we add T3 or take NDT, the blood tests cannot correlate with the blood tests which are for the use of levothyroxine alone. Levothyroxine alone is T4 - should convert to T3 (doesn't always efficiently). NDT contains T4, T3, T1, T2 and calcitonin.

If you stopped the T3 before your blood test, your TSH is still too high and the aim is 1 or lower so your dose was fine.

I shall give you a couple of links:

You are entitled to copies of your own results. Some surgeries make nominal charge for printing out.

Alternatively you can now ask for online access to your own medical records. Though not all surgeries can do this yet, or may not have blood test results available yet online.


Yes I managed to get (and paid) for this test result but every time I ask for previous ones they manage to 'not be available' - going to ensure get copies going forward but to be honest I've given up on them getting me feeling well so going to go my own way


Little bit off topic but I recently dodged a bullet re misguided blood tests.

As the world knows we recently had an election and I usually volunteer to work the Poll. We were ludicrously busy and I had just taken my last pill (NDT) so urgently needed to go and pick up my prescription. Just before we started work I dashed off to the Pharmacy, picked up my pills, had my obligatory blood test and went back to the mad house - I mean polling station.

The following morning I received this frantic e-mail from my doc telling me that my TT3 was in excess of the maximum, that my TSH was .01 and that, based on this result, I should reduce my dose immediately! It was then that I realized that I had had my blood test within a couple of hours of taking my pill. I, of course, emailed back right away telling him this and not to worry that T3 only has a half life of about 8 hours and that by mid afternoon I would konk out - it would be sub optimal by then. Geez I am glad I have read around this subject and that I am on this site, because, had I obeyed him I could have been ill and not able to walk for a year until he realized that I was on too low a dose.

But, of course, it is interesting to know some of your levels having just taken a pill, the other end of the spectrum that we rarely measure. He only does totals and TSH though, not very informative.
