Re: FT3 ranges in UK

[Guest guest]

Hi Al - we ALWAYS recommend that before having any serum thyroid

function tests, you do not take any thyroid hormone replacement the morning of

your blood draw. This is because T3 has a very short half life of only 2 days

in humans, and the effect starts to leave your body between 6 to 8 hours - this

is why for anybody taking either synthetic T3 or the T3 in natural thyroid

extract, we recommend taking it in split doses, half in the morning when you

wake, and the other half between 6 to 8 hours after that. This keeps the engine

topped up.

The T3 peaks in the blood between 2 to 4 hours after taking it

(depending on your metabolism) and if you have your blood drawn during that

time, the T3 spikes in the blood, often showing it is outside the top of the

reference range and as your GP has demonstrated, it knocks them for six and

they get scared you are taking too much. They should go by how you feel, not

blood te4st results. For anybody taking too much T3 they would know VERY

quickly and would not want to remain on that dose. This is the beauty of T3

products.

If you are seeing an endocrinologist, then insist that your GP

allows you to have another blood test on your thyroid function done (in case,

you can say, the first one was a mistake), only this time, don't take any

thyroid medication on the morning you have your blood drawn. The result will

probably be half what it was before, so panic over.

If only doctors would learn about what thyroid hormones actually

do and how they work, there would be no need for such panic.

Good luck.

So my GP is getting panicky over my FT£ range,

thinking I am over-medicated.

I take 90mcg T3, no thyroxine or Armour, hence a very low FT4.

My FT3 was 6.18 (range 2.63 - 5.7)

To me that is a good FT3, but he wants me to see an endo, so I have an appt

next week.

Can anyone point me to any references that say a FT3 over range is OK?

preferably from the likes of the BMJ.

I am definitely better on T3 only, but have no idea what the endo will say, so

I would like to go prepared!

Many thanks

My FT3 was 12.1 same ranges as yourself on 100mcg of T3. Which shows signs of

pooling

But over at the RT3 group they always say when on T3 only that you should be at

the top or even over the range. They reccommend when you are feeling at your

" best " regarding the dosage to then get a FT3 done to see were you lie in the

range.

Thanks all - I already take my T3 split, as per RT3 forum.

30mcg am, 35mcg 12:30, 25mcg 5:30, 10mcg bedtime. This is self medicating,

although the GP prescribes the T3 (Liothyronine Sodium)

On the day of the draw I did not take my am dose, so it was 12 hours since my

previous.

I still havent really got any " hard evidence " of an acceptable FT3 range, other

than reading anecdotally that it used to be a higher range than up to 5.7 (ish).

I imagine the conversation going along thew lines of ENDO : " you are over range

so must cut back on the T3 " and me replying - " yes but in *** journal it said

that a high-ish FT3 was good " You get the idea.

Oh well if nothing comes up will try and blag it!!!
