Free T3

[oldie]

For those trying to get their FT3 up: after two years low  my FT3 is now above half way at 1.47  (lab range 0.8-1.9 ng/dl). I've been following the same exercise/diet routine for all that time and taking 100mcg Levo for most of that time. The only change was I cut this to 75mcg in the past seven weeks in an attempt to stop the night hots an sweats. It didn't work. .

That's the best yet and I will try it out  at the next session with a cardio. The warnings on amio emphasize damage to lungs and liver, then thyroid. The cardio who put me on it left me without tests for 15 months, although US-trained.  He left his  heart clinic, and the city, under unexplained circumstances.  I just picked the wrong man.

This is my take on that question Oldie. This medicine would be compared to using an actual T4 thyroid medication on a thyroid that didn't need it.

On that case - it can be a permanent burn out of natural thyroid function is used and then medication would be needed for life to kepp what's left of the thyroid functioning normally.

You were right, Oct 16. My results are now  FT3    3.25   (range 2.02-4.43). I'm over the halfway mark for  first time in nearly two years levothyroxine.. But still getting some hypo symptoms.

A question I cannot get answered anywhere is whether a thyroid damaged by amiodarone (TSH 38) is damaged permanently or  recovers when it is brought to normal levels in tests?
Is a patient no pills for life if his hypo was caused by medication and then brought to normal?

Any thoughts or info please?

this is the first time the lab has used this range for FT3. two months ago it was 2.02-4.43  ng/ml with me at 2.74. In March it 2.0-4.43 pg/ml (sic) with me at  2.52,  I begin to have doubts.
Last week FT4 was 3.21  (2.05-4.43 pg/ml). I'll ch3ck with them. Thank you

I checked all those ranges before I posted.  The one I found for ng/dl was .23 - .42.  None of the others I located fit either.  The only range I found that was close was from one lab that listed .8 - 1.8 ng/dl, but it was for FT4.  So that is why I thought it should be double checked.

In Aus our unit of measurement for Free T3 is pmol/l   This gent is in Guatemala, where they use ng/dl  I am not good at the math, but believe he is in range if it were converted.

I've never seen an FT3 range like that.  Please double check and to see if it might be FT4 and the FT4 range.
