How do you work out your percentage through the range please?

0.27 - 4.2 R

2.4

mIU/L

FREE T3

3.1 - 6.8 R

3.7

pmol/L

FREE THYROXINE

12 - 22 R

12.6

pmol/L

How do you convert your results into a percentage of the total range please? I thought you took the top of the range figure as 100% then worked out 1% then multiplied by the result but I don’t think that’s the correct 🤷‍♀️

Thanks

use this helpful calculator

Your results show you have a thyroid problem

Was test done early morning to get highest TSH

Sorry your previous post didn’t get any response

This is a very busy forum

Thanks, no problem. I knew I had to stop b vits and folate prior to testing I just wasn’t sure about HRT and still haven’t decided yet. On reading I guess the key thing is consistency with the same regimen for every set of bloods. Just not sure if progesterone is possibly supporting my thyroid if it’s best to have a result without this in the mix.

So my percentages are

FT3 16% FT4 6%

I think I read in another post a higher FT3 means likely hypo. Does a higher FT3 mean I’m converting ok what little TS4 there is? Clearly there’s insufficient TR4 and as my TSH is creeping up my body’s asking for more thyroid hormones producing. Not surprising really!

Your TSH is not responding correctly to very low Ft4

So that suggests Hashimoto’s and/or low vitamin levels likely

Don’t stop folate before test…..just stop B complex

This Medichecks test was done at 10 am but I’d had a coffee first.

Just ran all my results to get percentages.

TSH 2.4 mIU/L (0.27 - 4.2) 54.2%

Free T4 (fT4) 12.6 pmol/L (12 - 22) 6.0%

Free T3 (fT3) 3.7 pmol/L (3.1 - 6.8) 16.2%

T4:T3 Ratio 3.405 

Folate - Serum 6.86 ug/L (3.89 - 26.8) 13.0%

Vitamin B12 78 nmol/L (37.5 - 150) 36.0%

Vitamin D 70 nmol/L (50 - 175) 16.0%

Ferritin 145 ug/L (13 - 150) 96.4%

So my thyroid hormones are low, I don’t understand the significance of the T3/4 ratio. I’m reading on other posts my poor vit levels could be due to coeliac disease?

I’m doing so much reading. I’ll work my way through the other links you provided.

Thanks

Pity there’s no thyroid antibodies tested

Folate - Serum 6.86 ug/L (3.89 - 26.8) 13.0%

Vitamin B12 78 nmol/L (37.5 - 150) 36.0%

Vitamin D 70 nmol/L (50 - 175) 16.0%

These are too low

Work on improving and retest including thyroid antibodies in 6-8 weeks

GP will often only prescribe to bring vitamin D levels to 50nmol.

Some 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 improving to around 100 -125nmol by self supplementing may be better

pubmed.ncbi.nlm.nih.gov/218...

vitamindsociety.org/pdf/Vit...

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.

One spray = 1000iu

amazon.co.uk/BetterYou-Dlux...

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

Low folate

supplementing a good quality daily vitamin B complex, one with folate in (not folic acid)

This can help keep all B vitamins in balance and will help maintain B12 levels too

Difference between folate and folic acid

healthline.com/nutrition/fo...

B vitamins best taken after breakfast

Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule)

Thorne currently difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay

Igennus B complex popular option too. Nice small tablets. Most people only find they need one per day. But a few people find it’s not high enough dose

Post discussing different B complex

healthunlocked.com/thyroidu...

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)

Low vitamins extremely common when hypothyroid due to developing LOW stomach acid

We need acidic stomach acid to absorb nutrients from food

Are you currently taking any medications or supplements

Thanks, I’ll read. No, no meds other than HRT and now supplementing b vits, folate and vit d since these test results.

I don’t eat lots of gluten generally I have more dairy but have ditched cheese and lattes since my cholesterol has crept above range. I understand this is another hypo symptom as well as gallbladder issues linked to the way thyroid controls cholesterol too. I get a pain under my right rib intermittently now too.

If I were a car I feel I’d have a gazillion warning lights flashing on mt dashboard but of course all the GP say is my tests are in ‘the normal range’ . I’m getting some further blood done soon as things have been getting gradually worse. I assumed it was because of the menopause but new symptoms like Raynuards are linked to thyroid and not menopause.

Raynuards - definitely linked to being hypo

As is high cholesterol

Fizzwhizz in reply toSlowDragon

Yes, I have so many clinical symptoms which are ramping up but GP still hidebound by blood tests in range.

I read all the links. Thanks.

I read the stuff on magnesium. Can you recommend a supplement people use? I’m not sure of my levels but it seems the general population don’t consume sufficient. I’m already supplementing with the better you vitd and k combo oral spray.

Thanks, your help has been invaluable.

All those symptoms that the GP was looking at in isolation along with bloods are building a picture. My resting pulse is average 63 bpm again slow and a sign of hypo. I intend to do the basal temperature testing too and get new bloods with antibodies etc. I read menopause is a common time for women to be diagnosed with thyroid problems too.,

Next step get thyroid levels retested including BOTH TPO and TG thyroid antibodies

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

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

Medichecks Thyroid plus antibodies and vitamins

medichecks.com/products/adv...

Blue Horizon Thyroid Premium Gold includes antibodies, cortisol and vitamins

Or both companies offer thyroid test without vitamins at lower price

Only do private testing early Monday or Tuesday morning.

You have been supplementing vitamin B complex to help improve low folate

Remember to stop vitamin B complex 5-7 days before test.
