Blood test results

[Aniba]

Good evening everyone

I’m a little confused about my private results I’ have got back today, any advice would be appreciated especially this time of the year.

TSH 8.89 (0.27-4.2 mU/L)

FT4 17.3 (12 -22pmol/L

FT3 - 4 (3.1-6.8pmol/L)

Although T4 & T3 are within range why is my TSH high?

My August results no T3 done

T4 22.3 pmol/L (12.0-22)

TSH 0.76mu/L (0.3-4.2)

I had short synachten test in August never got the results and then had another on Monday this week reason being I was just above basal level 450 and they wanted to check results again which I’m still waiting for.

Thank you

Are you still taking 100mcg levothyroxine every day and always same brand levothyroxine at each prescription

Presumably you have autoimmune thyroid disease also called Hashimoto’s diagnosed by high thyroid antibodies?

What vitamin supplements are you currently taking

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

Was test done as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test on both tests

Thank you for replying, still taking 100 mcg same brand of levothyroxineWas diagnosed Primary Hypothyroidism ,thyroid peroxidase 213 (0.34) January this year.

Currently taking Vitamin and within range, started to take advanced probiotic over the last three weeks.

Private blood test done at 6am, but took levothyroxine 12 hours before test.

Synachten test done at 2pm afternoon on an empty stomach.

Many thanks

thyroid peroxidase 213 (0.34)

So high thyroid antibodies confirms autoimmune thyroid disease also called Hashimoto’s

With Hashimoto’s levels can change quite a lot

Last dose levothyroxine should be 24 hours before test

So Ft4 is false high result….if left 24 hours Ft4 result would be lower

What were most recent vitamin D, folate, ferritin and B12 results and ranges

[Aniba in reply to SlowDragon]

That’s makes sense why levels can change, my latest Vit D is 68 nmol/LUnfortunately I just got told folate, ferritin and B12 were in range but that was August.

I’m waiting for the hospital thyroid results now, that was done the same time as the Synachten test, therefore that would make it about 20 hours from last dose of levothyroxine.

Thank you

Always get actual results and ranges on all results

Just being within range is frequently inadequate

Eg B12 range is typically 190-680.

Medics would say B12 at 200 or 600 is “normal”

But many patients on levothyroxine have symptoms of low B12 with B12 under 500

We frequently need optimal vitamin levels

What vitamin supplements are you currently taking

Vitamin D is not high enough at 68nmol

GP will often only prescribe to bring vitamin D levels to 50nmol. Some CCG areas will prescribe to bring levels to 75nmol or even 80nmol

leedsformulary.nhs.uk/docs/...

GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)

mm.wirral.nhs.uk/document_u...

But with Hashimoto’s, improving to around 80nmol or 100nmol by self supplementing may be better

Once you Improve level, very likely you will need on going maintenance dose to keep it there.

Test twice yearly via NHS private testing service when supplementing

vitamindtest.org.uk

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function. There’s a version made that also contains vitamin K2 Mk7

It’s trial and error what dose we need, with hashimoto’s we frequently need higher dose than average

I’m currently taking Vitabiotics 2000IU Vitamin D increased from 1000—2000 a week ago, but it sounds as though the vitamin D mouth spray is much better, so will order this as you say we need optimal levels of vitamins, thank you for the links these are interesting reads.

I never really considered my self having Hashimoto’s and agree levels can change.

Thank you so much for your advice it’s much appreciated

Merry Christmas
