Thyroid blood test results

[annie-1969]

I'm new here and would like some feedback on my results if possible please. I've recently had a blood test as I've been struggling with low energy levels and mood, I had a lobectomy 3 years ago but this is the first time I've had a detailed test. It looks like I have a low Vit D which I can supplement. My thyroid results I think look ok and are as follows, please could I get some feedback on them to confirm this. Many thanks for your help with this, it's a bit of a minefield.

THYROID STIMULATING HORMONE 3.13 mIU/L 0.27 - 4.20

FREE THYROXINE 12 pmol/L 12.00 - 22.00

TOTAL THYROXINE(T4) 64.9 nmol/L 59.00 - 154.00

FREE T3 4.21 pmol/L 3.10 - 6.80

THYROGLOBULIN ANTIBODY <10 IU/mL 0.00 - 115.00

THYROID PEROXIDASE ANTIBODIES <9.0 IU/mL 0.00 - 34.00

ACTIVE B12 35.900 pmol/L 25.10 - 165.00

FOLATE (SERUM) *2.81 ug/L 2.91 - 50.00

25 OH VITAMIN D *40.9 nmol/L 50.00 - 200.00

CRP - HIGH SENSITIVITY 3.81 mg/l 0.00 - 5.00

FERRITIN 37.5 ug/L 13.00 - 150.0

Many thanks

Annie-1969,

TSH 3.13 indicates your thyroid is struggling and FT4 12 is completely bottom of range. NHS won't diagnose hypothyroidism until either TSH is over range or FT4 is below range but I think you need to retest in 3-6 months as FT4 may slip below range. Arrange an early morning and fasting (water only) blood draw when TSH is highest.

Thyroid antibodies are negative for autoimmune thyroiditis (Hashimoto's).

Active B12 >35 is unlikely to be deficient but if you have the symptoms in b12deficiency.info/signs-an... go to healthunlocked.com/pasoc for advice as they're the experts on B12.

Folate is deficient. My GP prescribed 5mg folic acid for a couple of months to correct deficiency.

VitD 40.9 is insufficient. VitD is replete >75 and optimal 100-150. You can supplement 7,500iu D3 daily x 6 weeks then reduce to 5,000iu daily and retest in May.

Ferritin is optimal half way through range. You can raise ferritin by supplementing iron with 1,000mg vitamin C to aid absorption and minimise constipation. Retest after 4-6 months.

Hi Clutter thanks for your reply, that's really helpful. I will look to retest as you suggest in a few months time. In the meantime I will also look to supplement my folate and Vit D levels. Thanks again.

An active B12 test under 70 suggests you may have low levels

Vitamin D, folate and ferritin all too low

These low vitamins are likely due to you being hypothyroid after lobectomy

If you are not on any Levothyroxine then you need see if can persuade GP to prescribe

Dr Toft, past president of the British Thyroid Association and leading endocrinologist, states in Pulse Magazine,

"The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range - 0.2-0.5mU/l.

In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l.

Most patients will feel well in that circumstance. But some need a higher dose of levothyroxine to suppress serum TSH and then the serum-free T4 concentration will be elevated at around 24-28pmol/l.

This 'exogenous subclinical hyperthyroidism' is not dangerous as long as serum T3 is unequivocally normal – that is, serum total around T3 1.7nmol/l (reference range 1.0-2.2nmol/l)."
