Blood results - conversion problem?

Hello everyone. I am on 75mg of Levo, up from 50mg eight weeks ago. Just had my blood results back from Medicheck.

Eight weeks ago on an NHS check:

TSH: 3.68 (0.23-5), FT4 15.2 (9-23%), FT3 4.1 (3.5-6.5)

Today:

TSH: 0.37 (0.27-4.2), FT4 19.8 (12-22), FT3 4.09 (3.1-6.8)

So it looks like my FT3 has hardly moved at all despite the changes in TSH and FT4.

I'm really tired. And with a TSH of 0.37 I don't think the GP will raise my Levo dose to 100mg.

Other results were:

Thyroglobin 534 《115

T Perox antibodies 321《34

They are both really high and I thought be gluten free might change that.

Ferritin 91.2 (13-150)

Folate 9.86 (3.89-19.45)

Active B12 55.5 (37.5-187)

Vit D 121 (50-175)

I take Vit D/mag/K2. Stopped B vits 10 days before the test. Followed the protocol for the blood test.

I'm not sure what to do next. I have some T3 bought a while ago, but on advice here I didn't use it in order to see if I could convert a higher T4. Thank you!

You are a poor converter, yes. So it would probably be a good idea to add in a little T3.

Doubtful. But, even if it did, you'd still have Hashi's. And, once you know you have it, the actual level of the antibodies is irrelevant.

Thanks Greygoose. So this sort of confirms I am not converting well, I guess. Which is inconvenient because I will have to buy T3! I have two separate packs, one unipharma and one tiromel, both 25mcg. Should I try one a day, along with the 75mg of Levo? I haven't tried this before, but would like to know if I would feel better with T3 above 50% of the range.

Let's say that, all things being equal, you should feel better if the FT3 was above 50%. But, of course, there could be other problems affecting you, like low/high cortisol. But, it's certainly worth trying the T3

But, don't start on 25 mcg! That's much too high a dose to start on. Start with a 1/4 tablet for at least two weeks, to see how it suits you. If there are no problems, increase by another 1/4 tablet. You can increase like that until you get to 25 mcg, then hold for 6 weeks and retest. :)
