Does anyone know the website that works out percentage through range for T3 & T4

[ML44]

I had it, and I’ve lost it and it takes me forever to work out myself; maths is not my strong point!

TIA

Thank you so much!

Can you tell me how I use this tool? Many thanks

[SlowDragon Administrator in reply to Suin]

Results is left hand box Ranges in next two boxes

Eg

Ft4 result 14. (Range 12-22)

Three boxes left to right

14. 12. 22

Press the button

Gives result in % - 20% through range

[Suin in reply to SlowDragon]

Thank you

[Suin in reply to SlowDragon]

And what percentage are we aiming for?

[SlowDragon Administrator in reply to Suin]

Well everyone is different...but typically Ft3 at least 60% through range

Ft4 often needs to be at higher level in order to get Ft3 high enough, especially if conversion is poor

[Suin in reply to SlowDragon]

Thank you, last year my T3 is 66% and T4 0 %

[SlowDragon Administrator in reply to Suin]

On T3 only I assume

Obviously we need all four vitamins at optimal levels too

Previous post shows low ferritin levels

Yes, sadly we had a family tragedy and I put acting on my health on hold, so trying to have another look. I’ve a Thriva test kit ordered too, GP says they’ll only do my bloods annually. Thank you I’ll read that link.

[Suin in reply to SlowDragon]

No, I was on 125mg T4

[SlowDragon Administrator in reply to Suin]

You have put that Ft4 is 0% through range

If that’s really the result, you were extremely under medicated

[Suin in reply to SlowDragon]

FT4 0% T3 64.86%

[SlowDragon Administrator in reply to Suin]

So you are saying your Ft4 is only 12 in last result (assuming range is 12-22)

Either you’re extremely under medicated, or using calculator incorrectly

What are your actual results and ranges

[Suin in reply to SlowDragon]

Yes it T4was 12 range(12-22)

and T3 was 5.5 range ( 3.1-6.8)

[SlowDragon Administrator in reply to Suin]

Well you certainly need dose increase in levothyroxine then. Aiming for Ft4 at least 60% through range

[Suin in reply to SlowDragon]

I had reduced T3 to 20mg daily and T4 to 150mg over 2 months and am going to test next week.

I still feel absolutely terrible and hadn’t been on iron lately either.

Thanks SlowDragon and sorry I’ve jumped on the original post ML44

How odd is that? I was looking for the same thing on my tablet yesterday. I keep it on my desktop equivalent, but couldn't find it anywhere. Got on here to see your message! LoL Thanks very much.

[ML44 in reply to BrynGlas]

Once lost it’s near imposible to find!

[BrynGlas in reply to ML44]

Too true, that is why I am also asking if we have some way of putting things such things as this, or any links to press reports, etc etc safe so we can access then easily.

Have you seen the message, 'T3 - You couldn't make it up!' posted by Fruitandnutcase?

Very interesting.
