help to understand test results

[Mac2013]

After a year of monitoring my TSH due to a bout of subacute thyroiditis, initially suspected as thyroid cancer. I am now at a point where my GP feels medication may be required and have undertaken an extensive range of blood tests through the GP I have an appointment on the 4th July to discuss options.

I have been working with a nutritionist and herbalist for 18 months to try to get my thyroid and adrenals functioning well after a recent cancer diagnosis.

I tested privately using Medicheks for a full range of thyroid tests in March 23 and just done the same again this month as my GP has only been testing my TSH. Although I annually have a full panel undertaken since my endometrial cancer diagnosis two years ago.

Please see my medicheck results below:- (hope I’ve typed these out correctly

March 23 - Medichecks

TSH 0.48 miu/L (0.27-4.2)

FT4 22.6 pmol/L (12-22)

FT3 5.05 pmol/L (3.1-6.8)

T4:T3 ratio 4.475

TgAb 52 IU/ml (3.89)

Vitamin B12 150nmol/L (37.5. -150)

Vitamin D 163 nmol/L (50-200)

Ferritin 195 ug/L (13-150)

June 24 Results - Medichecks

TSH 5.03 miu/L (0.27-4.2)

FT4 14.8pmol/L (12-22)

FT3 3.1 pmol/L (3.2-6.8)

T4:T3 ratio 4.774

TgAb 18.2 IU/ml (0-115)

TPO 11 IU/ml (0-34)

CRP 2.420 mg/L (7)

Vitamin B12 150nmol/L (37.5-188)

Vitamin D 137nmol/L (50-250)

Ferritin 55ug/L (30-332)

I have several variants on my genes as outlined in my bio which I hope helps. I welcome any help as I’m really struggling at the moment as to how to move forwards. Many thanks.

As you can see your results have plummeted so I can imagine you feel pretty grim!

Your vits and mins look good except for your low end ferritin, worth getting a full iron panel to see if supplementing is the way to go

TSH 5.03 mIU/L (0.27 - 4.2) 121.1%

Free T4 (fT4) 14.8 pmol/L (12 - 22) 28.0%

Free T3 (fT3) 3.1 pmol/L (3.2 - 6.8) -2.8%

T4:T3 Ratio 4.774 

Yes time to start treatment

Thank you. To be honest I’m not feeling grim but definitely felt better in 2023. Will ask for full iron panel.

[TiggerMe in reply to Mac2013]

Possibly your adrenals are holding you up at the moment but once they start to struggle things get a whole lot tougher

[Mac2013 in reply to TiggerMe]

Yes, possibly - I’ve been working really hard on adrenal support since my endometrial cancer as testing revealed they were flatlining in 2022…… not tested again but maybe from what you’re suggesting that side of what I’m doing is working right now.

[TiggerMe in reply to Mac2013]

Dr Peatfield's book highlights that we should support adrenals before supporting the thyroid so you are one of the few to get it in the right order and will likely have a pretty easy ride when you add some thyroid hormone 🤗

I always look at FT3 first based on my personal experience/ thyroid isues and you are seriously deficient in what is one of the body's most important hormones....T3

You must be feeling rubbish!!

TSH is not a reliable marker ( research shows) so your GP needs to up his advice/ testing and understand that for good health every cell in the body must be flooded with T3 by way of an adequate and constant supply.....your labs show neither is happening!

You absolutely need replacement thyroid hormone(s) or your health will suffer

Starter dose 50mcg levothyroxine...

test after 6 weeks

increase dose to 75mcg levo

test again after 6 weeks then...

review dose...

you most likely need to raise to 100mcg levo but first post labs here 6 weeks after increase to 75mcg for advice before increasing further

These labs will then show if conversion is poor ( high FT4 with low FT3) It is not obvious at this point

Are you saying that you have the Dio2 polymorphism which has the potential to affect T4 to T3 especially if inheritance is homozygous ( Panicker et al)

Hope your GP helps

[Mac2013 in reply to DippyDame]

Thank you. It’s strange I’m not feeling rubbish but know I could feel better. Yes, my genotype which affects T4 to T3 conversion not sure if homozygous or not?

Do you have a folate result?

I’d recommend starting treatment at 50 mcgs levo.

[Mac2013 in reply to Jaydee1507]

Thank you

My serum folate was:-

19.98 ug/L (>3.89) in 2023

And

33.1 nmol/ (range >7) in 2024

Not sure how I missed those…… 🙃

[Jaydee1507 Administrator in reply to Mac2013]

That looks good.

Ferritin still needs some work. Optimal for ferritin is said to be 90-100.

Suggest increasing iron rich foods in diet and eating them often. Chicken livers, pate, red meat etc

[Mac2013 in reply to Jaydee1507]

Thank you. I’ll put focus on that.

[Mac2013 in reply to Jaydee1507]

Can’t seem to access the link.

Click on where it says iron food. The page seems to have moved.
