Results post if anyone could please advise

[VanessaB]

I put a post up about my thyroid check from medichecks the Gp has written that I need to ask my doctor for a reduction as my TSH is 0.023 I last had a reduction in March as my GP goes on Tsh only.My last Tsh was 0.5 in July with ft4 15.3.But when they drop my dose my ft4 goes very low but Gp says ft4 is not important.I know that when my next thyroid tests are done he will want to reduce again.I have been on iron tablets so not sure if that accounts for Tsh going low and ft4 going up.I just want to be on a stable dose.If anyone could advise on results as the doctor says apart from Low TSH everything is fine.

Unfortunately, the doctor's comments with these private tests will toe the same line as any NHS doctor. I never request the comments, patient experience on here gives us a lot more understanding of interpreting tests.

You do not need a dose reduction. Look at your FT4 and FT3 not theTSH. The TSH is low because you are taking thyroid hormone replacement and your pituitary gland is recognising this so doesn't need to send a signal to your thyroid to produce any hormone - that signal is TSH and it would be high if you didn't have enough hormone.

So FT4 is well within range, as is FT3. Look at the FT4: FT3 ratio - 19.3 : 4.53 = 4.26 : 1

Good conversion takes place when the ratio is 4:1 or less, so your conversion could be better. Opptimal vitamins and minerals will help, as will taking selenium L-selenomethionine 200mcg daily.

Your folate is far too low, it should be at least half way through it's range.

Your Vit D should be between 100-150nmol/L.

Your ferritin should be at least 70.

Your raised antibodies also confirm autoimmune thyroiditis aka Hashimoto's and you need to address this. You can help reduce the antibodies by adopting a strict gluten free diet. The selenium will also help reduce antibodies, as will keeping TSH suppressed.
