Low ft3

[Itileguy]

Increased to two grains of armour medicine but my ft3 dropped from 3.1 to 2.9

What gives

[greygoose]

I think we need a bit more detail to be able to suggest a reason:

How long were you on 2 grains before you tested?

What were you taking before?

Were this test and the last test done under exactly the same circumstances: same time of day, same gap between last dose of NDT and blood draw?

Do you have Hashi's?

[Itileguy in reply to greygoose]

I was taking 1 grain and 3/4 quarters of a grain

Then increased for 6 weeks to two grains

Yes same time

No hashi

Maybe needed to be on it longer

[greygoose in reply to Itileguy]

Well, 1/4 grain only contains 2.25 mcg T3, so you wouldn't expect much of an increase, anyway. And, could be that you're just absorbing more than usual at a cellular level - have you been more active lately? But, the difference is so slightly that it's nothing to worry about. You're bound to get variations at times.

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

If/when also on NDT make sure to take last third or half of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test

Is this how you do your tests?

[Itileguy in reply to SlowDragon]

I take mine at 4:00 am

So I took my dose on Tuesday

No Wednesday dose that morning then tested at 10:00 am

Then took medicine

So that would of been almost 30 hours since last dose til testing

Did I do it wrong ?

[SlowDragon Administrator in reply to Itileguy]

so you will have false low Ft4 and Ft3 results

On day before test you should take half or third of daily dose 8-12 hours before blood test

[Itileguy in reply to SlowDragon]

Ok thank you

[greygoose]

No, that would be 0.5 grains. More or less.

1 grain contains 9 mcg T3.

9 divided by 2 is 4.5.

9 divided by 4 is 2.25.

[greygoose]

No problem.

It would be nice if you can get a RT3 done at the same time you do the FT3/FT4..Both your FT3/FT4 are low. Your FT4 "could" be going to RT3. "IF" that's the case then we

would know your not converting. This would lead down the path of either a cortisol and/or iron issue?

[Itileguy in reply to aspenca]

I know iron is ok

Cortisol, I have never had tested

I have a appointment with a functional doc in a month

So hopefully it will be better

Hey there Itileguy

Do you feel any different ?

NDT is more about the relief of symptoms rather than blood test numbers :

It's such a marginal difference, just a twelfth less than where you were :

If still with symptoms of hypothyroidism I'd just keep nudging up as you were doing monitoring temperature and blood pressure and see how you go increasing from 2 grains :

[Itileguy in reply to pennyannie]

I have an appointment with a functional doc in a month so I’m hoping she will be more understanding with symptoms and dose

[pennyannie in reply to Itileguy]

That's a long time to wait - why not nudge up a little and see how you go - you know your body better than anybody else and a bunch of numbers from the blood test report that aren't actually relevant when dosing with NDT.

As long as the T3 stays in range, you'll feel better when it's up near the top - mine comes in at just under or just over the top of the range - I feel no different and am not hyper but well.

[Itileguy in reply to pennyannie]

I could do that I actually have a stash of extra armour to get me by til appointment

😊

[Itileguy in reply to pennyannie]

Well I got on 2 grains for 8 weeks and my new functional doc did blood and is ok with me staying on 2 grains and I feel fantastic

Thank you so much for the conversation back and forth
