Thyroid Blood Test Results

[Bess48]

Hi would anyone be able to advise me please I’ve just had my thyroid blood test results back and my TSH is 0.07 (range 0.30 - 5), my T4 is 11.1 (range 11.5- 22.70) and cortisol is 575 the NHS didn’t do my T3 but my previous result which I did with Medichecks back in March were TSH - 0.02 (range 0.27 - 4.2) T3 - 4.57 (range 3.1 - 6.8) T4 15.4 (range 12-22) thyroglobulin antibodies 21 (range <115) thyroid peroxidase antibodies- 99 (range <34).

I am taking 1 1/2 grain and 1 grain every other day alternating ie 1 1/2 grain Monday, 1 grain Tuesday, 1 1/2 grain Wednesday etc. With these new NHS blood results is this enough as I’m constantly tired I’m on NP Thyroid?

Any advice would be appreciated thank you x

Firstly NDT should be taken with the same dose at the same time every day. Its only Levo that can be taken alternating as T4 is a storage hormone. NDT contains T3 which is an active hormone and the same amount must be taken every day.

When did you take your last dose of NDT before this test? Ideally you should split it and take the last dose 8-12 hours before the blood draw.

We really can't tell much from either test as you need to get to taking the same dose each day.

What supplements are you taking?

What are your latest results for ferritin, folate, B12 & D3?

Hi Jaydee1507 thank you for replying to me the endocrinologist told me to take my NDT half an hour before my blood test I took it at 8.30am and my blood test was at 9am.

Serum ferritin is 47 (range 10 - 291)

Serum folate is 16.1 (range 3 - 19)

Vitamin D is 103.9 (range 50 - 250)

B12 is >150 (range 37.5 - 150)

I take selenium and zinc, Q10 with pharma nord and multivitamins with Biocare

Either your Endo is setting you up to fail or they don't know what they are talking about.

Your FT3 is only at 39% and needs to be in the region of 70% so no wonder you have symptoms. Your actual stable blood level is likely a lot lower than that as usual dose timing would be last dose 8-12 hours before blood test.

You really need to start by taking the same dose every day, probably 1 1/4 grains and split the dose morning and evening or morning, late afternoon & evening.

Multivitamins are not recommended in this group for a number of reasons, including being too low a dose to raise levels to optimal, including iodine which is not recommended when hypo and including iron which prevents absorption of the other vitamins and should be taken apart from other vitamins/Levo.

You would likely be better off with a good quality B complex. This B complex has all the right vitamins at a not unreasonable cost for 90 days supply. amazon.co.uk/Liposomal-Soft...

Ferritin should be around 90 - 100 for best use of thyroid hormone. Suggest increasing iron rich foods in diet and eating them often. Chicken livers, pate, red meat etc

Thank you for your help I will try the 1 1/4 grain each day and look at the link you sent me x

Hello Bess :

When taking any form of thyroid hormone replacement containing T3 you must be consistent and take the same dose every time so I do no think it advisable to be changing your dose of NDT every other day - why are you doing this ?

On NDT the blood test present differently to when on T4 - Levothyroxine :

Your TSH will likely be low suppressed and your T4 proportionately lower BUT your T3 should be proportionately higher than when on T4 monotherapy.

Was the Medicheck result on NDT or synthetic T4 ?

How long have you been on the NP Thyroid and have any symptoms been relieved ?

No thyroid hormone replacement works well until the core strength vitamins and minerals of ferritin, folate, B12 and vitamin D are up and maintained at optimal - do you hae any current readings and ranges ?

Hi Pennyannie thank you for your reply my endocrinologist said to alternate the dose every other day, the medicheck result was on NDT, I’ve been taking the NP thyroid since 2019 I was previously on nature throid but then I was unable to get it so had to switch to NP thyroid which I have been on since.

My symptoms haven’t really improved and I’ve also lost a lot of weight, my other results are;

Serum ferritin is 47 (range 10 - 291) 

Serum folate is 16.1 (range 3 - 19)

Vitamin D is 103.9 (range 50 - 250)

B12 is >150 (range 37.5 - 150)

Hello there :

First and foremost you must make sure when you reply to any particular person that you press the reply box alongside their reply to you as then they get notified, otherwise it's pot luck if they see your reply and you end up feeling ignored, which is not a word anyone should suggest this forum is.

OK - well I disagree with your endo's advise.

Your ferritin is much too low and needs to be up and maintained at around 100:

Everywhere I researched suggested ferritin needed to be at least over 70 for any thyroid hormone replacement to work well and once I built up my ferritin, I totally agree with this statement.

As for the others I aim for a folate at around 100: active B12 75 ++( serum B12 500++ ) and vitamin D at round 100:
