I would really appreciate your views on my latest blood results .? I am really confused and don’t know what to do next, I had been trialling T3, but endo consultant(private) said he did not think T3 was helping so to go back to my original dose of 125g thyroxine, I had been taking 75g + 10 of T3 split into 2 doses of 5g. These are my blood results since doing that, but I feel very lethargic and.needing to rest frequently when doing anything .
Any help you could give would be really appreciated as I am wondering whether it is worth going back to consultant as he said he did not think it had anything to do with my thyroid.!
Thank you so much

If so how long after stopping T3? Testing should be 6-8 weeks after any dose change.
Can you please confirm whether or not you did the test as we advise, ie
* Test no later than 9am
* Nothing to eat or drink except water before the test
* Last dose of Levo 24 hours before test
* If test was done when still on T3 then the day before the test you split T3 into 2 doses and took the last dose 8-12 hours before the test
* No biotin, B Complex or any supplement containing biotin for 3-7 days before the test
If so we can interpret your results as follows.
It's not easy to read your results.
TSH: can't see one
FT4: 21.2 (10-20)
FT3: 4.6 (3.5-6.5)
Why did your endo say your trial of T3 wasn't working?
These results (if test was done as above) show that your FT4 is too high and FT3 too low. This suggests too much T4 and not enough T3 and your endo should maybe have suggested increasing your dose of T3 rather than stopping it altogether. Your low T3 will be causing synptoms.
If test was done taking 75mcg Levo plus 10mcg T3 then that's rather a high FT4 level for what is a relatively small dose of Levo and I'm wondering if you took your Levo before the test on the day and it's given a false high result by measuring the dose just taken rather than the more accurate normal circulating level obtained by not taking your dose before the test.
If test was done on 125mcg Levo only then the results show poor conversion of T4 to T3.
Your full blood count looks OK and doesn't suggest anaemia.
Vit D: 72.5 (I think) nmol/L
This is on the low side, the level recommended by the Vit D Council, Vit D Society and Grassroots Health is 100-150nmol/L with a recent blog post on Grassroots Health recommending at least 125nmol/L.
Do you supplement with D3? If so how much?
Bone profile looks OK.
Folate looks good, do you supplement with B Complex or methylfolate/folic acid?
GFR: flagged as it's low. It's not something I can comment on but hopefully your doctor has discussed this with you.
Testing Ferritin and B12 would be very helpful, we need optimal levels of all key nutrients for thyroid hormone to work properly. Ferritin is particularly important.
Endo said T3 was t working cos I didn’t feel any improvement
Did he do thyroid function tests at the time - TSH, FT4 and FT3? Do you have those results to compare to levels before T3 was added? I wouldn't be surprised if the endo didn't give you a long enough trial or increase your T3 to an appropriate dose.
I have been taking supplements. D3/K2
4000iu K2 100. Stopped taking them 8 days before blood test
No need to stop before testing. We need to know what level our dose is achieving so we continue and on the day of the test take after the blood draw.
Yes I’m taking Thorne Basic B Complex
👍
GFR. This will be showing low as I have 1 kidney
Ah, OK, no need to worry then as you know the reason.
Don’t think they tested Feeritin, but B12 is 618
B12 looks pretty good, maybe try and get ferritin included at some point.
Adding T3 certainly seemed to improve your FT3 level so I'm puzzled as to why the endo said it wasn't working. The fact that you said you didn't feel an improvement should have prompted him to look at your key nutrients - Vit D, B12, Folate and Ferritin - and optimise those if needed and tweak doses of Levo and T3 to enable you to find your sweet spot.
Do you have full thyroid and vitamin results/ranges from this time? It would be interesting to see and try to understand why he did what he did.
Do you think I should go back and ask to be out back into T3 and try it for longer
Do you have enough faith in him to do it right? You might be better with a different endo. You can always ask for recommendations of a T3 friendly endo to be sent to you by private message. You can also send for the list of thyroid friendly endos from ThyroidUK by emailing
He didn’t ask for key nutrients, but asked gp to check for calcium, blood count, ESR, and electrolytes. I only have my TSH, T3, and T4 results from that time, unfortunately.
I'm wondering if this endo is worth you paying to see him. He doesn't seem to be taking everything into account.
You can always get your own private tests done, as many of us here do. because we can't always get them all done with GP. Monitor My Health, Medichecks, Blue Horizon, they all offer thyroid/vitamin panels. It's as important for you to know these levels and understand how important they are as well as the endo.
You know your Vit D level and what you need to do. You know your B12 level which is fairly good. You need to know your folate level because B12 and folate work together. It is most important that you test ferritin, low ferritin means poor conversion. Some experts say the optimal ferritin level for thyroid function is 90-110ug/L.
You also know your conversion on Levo only is very poor
You need an over range FT4 to produce a pitiful FT3 level that is 36.67% through range. So first of all find out if ferritin is a problem, if it is address it. And if these were my results I'd be looking to add T3 back, building up to a dose that makes me feel well. You need a lower FT4 and a higher FT3.
