Best T4 & T3 levels for Hashimoto's?

From: pritcharddesign - 1 year 23 hours ago

I was diagnosed with Hashimoto's last April and have been seeing an endocrinologist (followup today). I just got results of recent blood tests. My Free T4 is 0.9 (normal range 0.8-1.8). I'm thinking it should be higher? What med replaces T4?

That is low. What is your FT3? What is your RT3? T4 is an inactive hormone. T3 is the actual active thyroid hormone that your body uses for cellular energy. My guess is that your FT3 is also low, but we would need to know for sure. Have you had the other tests?

Oh and I meant to say that the best FT3 levels for pretty much anyone, is going to be in the top three quarters of the range, of whatever ranges they are using at the particular lab you get your testing at.

So sorry I never came back, Viv!

I just had more blood work done and my Free T4 is 1.1 (0.8-1.8 is normal)!
TSH is 1.03 (0.4-4.5 is normal)
T3, FREE is 3.2 (2.3-4.2 is normal)

In fact, I had a huge workup and EVERYTHING is right down the middle of normal. Even before Hashimoto's diagnosis, that's how my blood work has always been. And I've been tired since I was a teenager.

Now with H, my nails are dry and split; my body gets very tired, weak, and sore when I walk up a flight of stairs (or anything, really, after sitting for a bit); my feet HURT after lying down for a while...it's all very depressing.

I'm taking Levothyroxine (Synthroid) 75 mcg and Liothyronine (Cytomel) 10mcg (when I don't forget!).

Thank you
