Hoping for help with blood tests

Hoping for help with blood tests

I would really appreciate some help on these blood test results.

I can see FT3 is way down, but my FT4 looks a bit higher than I would have expected with that FT3 result. Am I wrong on this, or does it possibly indicate a conversion problem?

It looks to me as if my Vitamin D is sub-optimal (it hasn’t shifted at all since the last test in December, despite my taking 3,000iu per day), so I’m temporarily upping my dose. Similarly my iron is a little low, so I’m temporarily upping my supplementation there.

My TG antibodies have come down from c350 a year ago, presumably due to my having adopted a gluten free diet. I supplement B12 daily, hence the high level there.

I’ve been on 50x5 and 75x2 mcg levothyroxine per day; a week ago, after receiving these results, I upped it to 50x3 and 75x4, and have been feeling like death warmed over ever since. Hopefully that’s simply the temporary post-increase worsening that so many people seem to get.

Thanks so much for any help anyone is able to offer.

Are you on gluten free diet as you have high antibodies?

It might help reduce symptoms, and slowly lower antibodies, along with selenium supplements.

Thank you, yes, I am gluten free. In fact my antibodies have come down over the past year from c350 to c200, which I think is mainly due to this. I do supplement with selenium, but it's been a case of once every few days due to the cost of taking so many different supplements - I'm now trying to make sure I take it every day.

Thanks for the help!
