blood tests for without a thyroid

[Edowds]

I would like to know what should be tested in my annual Thyroid blood test as I had TT 60 years ago and I am feeling very under medicated at the moment?

How much levothyroxine are you currently taking

Do you always get same brand levothyroxine at each prescription

What vitamin supplements are you currently taking

When were vitamin D, folate, ferritin and B12 levels last tested

what are your most recent thyroid and vitamin results

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

 

For full Thyroid evaluation you need TSH, FT4 and FT3 tested.

Very important to test vitamin D, folate, ferritin and B12 at least once year minimum

Low vitamin levels are extremely common on levothyroxine, especially as we get older

Recommended on here that all thyroid blood tests early morning, ideally just before 9am and last dose levothyroxine 24 hours before test 

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

I’m taking 125m thyroxine at the moment and no I don’t always get the same brand in fact my latest prescription is different again and one that I haven’t had before fortunately I hadn’t started it before my blood test yesterday and I’m glad to say the tests you mentioned are the ones I asked for and the nurse asked my how I knew about the tests I should have and I told her I had done my own research but she still had to go and check with a doctor and I’m pleased to say he gave the ok. I’ll post results when I get them. Thanks for your help

Looking at previous post

are you still prescribed T3 ?

Day before test, split T3 into two or three smaller doses spread through the day and last dose approx 8-12 hours before test

Thanks for replying, no the GP stoped my T3 because T4 dropped GP’s just don’t understand thyroid problems and I have more understanding now myself so depending on blood result I could be asking for T3 again

Hallo, same boat here. TT done in 2011, I only have my FREE T3 and FREE T4 tested was diagnosed with Hashi's originally, am on T3 only. Your TSH will be below measured levels, so no worries there.

I split my dose into 4 each day.

thanks for replying I was given a trial of T3 but as you say TSH dropped and GP stopped it but I have better understanding now and depending on blood results I could be asking for it again
