Hello,
I would be grateful for some advice regarding these results.
The background is that my Levothyroxine dose was reduced from 100mcg to 75 in early February 2024, due to a TSH only test which was below range. By late March I could barely function so I had a private test prior to the GP's TSH test. I informed the GP Practice of the private test results and requested a trial on 100mcg with a follow up full thyroid function test in 6-8 weeks, which was agreed, but in the event the lab only did TSH and free T4. The doctor wanted to reduce the dose back to 75 but agreed when I explained how ill I had been on that dose to let me continue for a further 6-8 weeks on 100, followed by another test. As I suspect they will only test TSH I have now had another private test.
These are the three test results. All were taken early morning 24+ hours after last dose of Levo.
Date: 30.03.24 (Private)
TSH: 0.189 (0.27-4.2)
Free T3: 3.8 (3.1-6.8)
Free Thyroxine: 18.8 (12-22)
Date: 31.05.24 (NHS)
TSH: 0.02 (0.10-4)
Free T4: 22.7 (9.00-22)
Date: 22.07.24 (Private)
TSH: 0.026 (0.27-4.2)
Free T3: 5.4 (3.1-6.8)
Free T4: 27.1 (12-22)
On the test on 30th March my free T3 was very low. Now it seems to be about right but the free T4 is very high. Might this indicate poor conversion?
In spite of the high T4 I have no palpitations or anxiety etc., though I do feel tired. I also still have hypo signs, e.g. very dry skin, vitiligo and think I may have an enlarged tongue as I frequently bite it!
I'm having the NHS test tomorrow and a GP appointment when results are back, so would be very grateful for advice before that.
Many thanks.
