Blood Results are in- now taking NDT and T3

Background- Graves and have had RAI

Now taking T3- 12.5mcg and 1 1/2 grains of NDT (Thyroid S)

Just took a private blood test and these are the results with ranges

TSH - 0.01 (0.02-4.2)

T4 - 11.0. (12.0- 22.0)

T3 -5.4. (3.1-6.8)

Room for improvement or should I leave things alone. It's taken a long time to feel close to 'normal' again and don't want to go back to the drawing board. Apart from feeling a little cold, constipated and I hair falling out I feel OK.

Thank you for your responses.

SophiaR, If you left 24 hours between last dose and blood draw and you are still symtomatic there is room for a small increase as FT3 isn't quite in the top third of range. Either half a grain Thyroid-S or 6.25mcg T3.

Thank you for responding Clutter. Yes I left 24 hours before drawing blood.

I will try raising the NDT and see how that goes.

The T4 being below range - is that something to be concerned about ? That should raise once I raise the NDT... Also the TSH which is suppressed already will that become undectable? Sorry I am getting a bit confused with all this as there are so many matters to look out for.

Thank you

Sophia, TSH will go lower when you increase dose. TSH 0.75 is low, not suppressed. Suppressed is <0.04. Increasing dose by half a grain is unlikely to make TSH undetectable.

The T3 and T3 in NDT are why your FT4 is low. FT4 is a storage pro-hormone and high levels aren't needed for conversion when you are taking T3 orally. Increasing NDT won't necessarily increase your FT4.

My TSH is 0.01.... So raising NDT could render my TSH undectable. Does that matter ?

I should not worry therefore and rely on T3 and T4 readings?

Thank you and I am very grateful for your help and direction Clutter.
