Hi all

I’ve just had my most recent results back can someone please advise on my thyroid as I’m not sure what my t4 should be if taking combination as it quite low?

My t3 is still only mid range too I was hoping that would have increased

I have had a positive result on the dio2 so am being trialled on t3

Still having lots of symptoms eat a clean diet and take supplements to include magnesium B complex vitamin D and selenium

I’m now on 20 t3 and 100 t4 have been taking t3 for 12 weeks now

T3 4.7 (2.8-7.1)

T4 11.7 (9-26)

TSH 0.02 (0.27-4.2)

B12 565 (191-663)

Folate 8.1 (3.3-19.3)

Ferritin 118 (10-150)

Vitamin D 99

My crp is still elevated at 14 (< 11)

And plasma viscosity is high at 1.85 (1.5-1.72)

How do you normally take your T3

As single dose or split into 2 or 3 doses?

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 .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

If/when also on T3 make sure to take last half or third 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?

Do you have Hashimoto’s

If yes are you on strictly gluten free diet

So this is the first test I’ve had done since being on t3

Tests were done in the morning I never take my meds beforehand

It’s a single dose as I didn’t find splitting it made any difference

The last t3 dose would have been 24 hours earlier so no I didn’t take anything 8-12 hours prior to testing what difference does this make?

Consultant never mentioned this

I have ords thyroditis and yes I am GF

Do you think my t4 is now too low as I’ve dropped from 175 to 100

Might not make any apparent difference to you but gives smoother delivery

you MUST split dose day before test as T3 only lasts in blood 12 hours so as you left 24 hours you have false low Ft3 result

Yes likely Ft4 dropping too much

Usually endocrinologist only drops levothyroxine by 25mcg when adding T3

How high was Ft4 on 175mcg ?

Ok thank you

T4 was high nearly upto top end of range but wasn’t ever over

I think t4 doesn’t suit me the more I take the iller I feel but I still feel rubbish on the combination dose!

I’m considering taking more t3 and dropping t4 lower but I have a private endo appt Wednesday so am going to see what he suggests I just want someone to see me rather than a virtual appointment

Have PCOS too latest scan revealed I have multiple follicles on both ovaries and I’ve not had a period since March I’m 42

I ache constantly

Inflamed joints

Bloated

No energy

Get out of breath/heart palps

Massive weight gain especially upper back clavicles tummy area

I really thought t3 would help but it hasn’t

Are you on strictly gluten free diet?

It takes months for T3 to settle and improve things...don’t change too much too quickly

Suggest you try splitting dose into 3 smaller doses at 8 hour gaps

Bloating and aching joints suggests gluten intolerance

Yes I’ve completely cut out gluten I will try splitting the dose
