Is someone able to explain why I feel unwell if my t3 is converting but t4 high. I did take the t4 two hours before as it was suggested I try this, but my t4 was also above range in March 24 following all the protocols on here for tests (both monitor my health tests).
GP test in between these showed normal t4,t3 and TSH (I took t4 in error before test this time also).
I know this is an NHS laboratory so this is why I choose them to try and be as near to GP results as I can.
My anaemia test failed with them due to clotting so I have to retest.
Thank you for any help and advice you are able to give.

This higher level of fT4 ( even though false you were high last time when correct timings used) hasn't improved your conversion so of no benefit, I'd be looking to decrease as over the top fT4 is known to be bad in the long term

FT3: 5.3 pmol/l (Range 3.1 - 6.9) 57.89%
Well, let's just say that some of your T4 is converting to T3, but not very much. That's an awful lot of T4 for relatively little T3. And could be you're one of those people that react badly to high levels of T4. Plus T3 that is too low - you'd probably feel better if it were around 70% through the range instead of only 58%.
Plus the fact that what little T3 you have has been downgraded by the deiodinase that causes poor conversion, so it's not as effective as it should be.
All this to say that you need to reduce your levo, see what effect that has on your conversion, and if it doesn't improve, you will need to procure some T3 to add to your dose of levo.
