    High T3/FT3 on Latest Labs & Low FT4...Any thoughts?

    I got my latest labs and I don't talk to my doctor until next week, so I'm curious about what these numbers mean and what I should be asking my doctor. Since my FT4 is so low, do I need more T4? With my FT3/T3 so high, does it mean the T3 isn't getting into the cells but pooling up in my blood (because of the reverse T3)?

    I'm being treated for hypoT and adrenal fatigue. About a week ago, I went through 2 weeks of feeling really hyper, agitated, fast pulse and elevated anxiety. Now I've been calmer, but I'm fatigued, sleepy, my muscles ache and the brain fog is worse. The only change in my thyroid med between the labs was the addition of 5 mcg Cytomel in the afternoon. I have been on 60 mg Armour since November. Also added between labs was 3,000 iu of Vit. D3. I also took myself off of Pravachol (cholesterol lowering drug) 1 month ago to see if it eliminated the aches in my legs. At first I thought it was helping, but now the aches are back and my cholesterol is worse.

    Thanks!!

    My labs:
    Now
    TSH - 0.14 (0.30 - 5.00)
    FT4 - 0.7 (0.6 - 1.6)
    FT3 - 490 (230 - 4 2 0)
    T3 Total - 243 (60 - 181)
    Reverse T3 - still pending

    December (same ranges as above)
    TSH - 0.16
    FT4 - 0.6
    FT3 - 333
    T3 Total - 158
    Reverse T3 - 251 (elevated)

    you are getting way too much T3 you are hyper !!
    I would cut out the Cytomel and maybe add some T4 meds, your FT4 is on the low side.
    I would call my doctor right away !!

    Are you on a T4 supplement. Your FT3 was optimal if the range was the same.

    Now
    TSH - 0.14 (0.30 - 5.00)
    FT4 - 0.7 (0.6 - 1.6) Still way to low. 10%.. not enough. You need to get this up and then see where the T3 settles to as your conversion rate stabilizes.
    FT3 - 490 (230 - 4 2 0) Way to high.. you need to stop the T3 and look to T4 supplementation.
    T3 Total - 243 (60 - 181)
    Reverse T3 - still pending

    December (same ranges as above)
    TSH - 0.16
    FT4 - 0.6 This is 0% if same range applies. You need T4!!! It looks like your T4 is all getting converted to T3 to keep things function.. but this means that T4 dependent functions suffer as a result.
    FT3 - 333 [[333-230]/[4 2 0 - 230]]*100 = 54%.. there is no need to think T3 supplementation is needed.
    T3 Total - 158
    Reverse T3 - 251 (elevated)

    Ugh! Sorry you are going through this.
