Blood work interpretation and newbie questions

Hello!  I had a thyroidectomy in March of this year due to confined pappilary tumor. No rai.  I just had my first blood draw. I was wondering if anyone would be willing to give me some insight. My doc will only test for Free T4.  I'm currently on 137mcg of Levothyroxine.  I was briefly diagnosed with Hashimotos before the biopsy.  My antibodies were 404 then.  I'd like to be put on Armour. My doctor is cool with that, but he wants to wait another blood draw before switching. I'm curious if my medication is too low as I've read a high Free T4 can mean that the T4 to T3 conversion isn't happening well.  Thoughts?

Here are my numbers:

TSH .34 (L)

TgAB 5 (H)

Free T4 1.7 (N)

Is your doctor recommending TSH suppression therapy?  If so, then you need to ask the target range for TSH.

That's really all that matters in the name of thyroid cancer management.

Note that TGAB is higher than supposed to (less than 4 IU/mL) ], so the Tg level might not be telling the whole story, as Tg is being attacked by antibodies (although a very low amount of them).

Good point.  Make sure you get your TG measured at an appropirate lab; one that knows how to measure with Tg antibodies. 

Since you have Hashi's, you'll really want to get your Tg history measured with the correct assay and stick with that same assay (until there are tech. advances).

Good luck!

If you don't do well on T4 only, numbers like a FT4 of 1.7 can leave such people very sick. I am certainly sick at those numbers, and very much so. When the FT4 starts going up higher in the range I immediately start getting HYPER symptoms, plus I get HYPO symotoms.

I take NP Thyroid currently, in three doses to solve that issue. So it is a bit more work going to 2 or 3 doses per day, but in general a person on NDT might run numbers like FT4 of 1 or 1.1 and FT3 of 3.5 to 4. This is where I do well.
