Please can I have some advice on my latest set of test results? I requested the Vit D, ferritin, folate and B12 to be done alongside my normal thyroid. I am currently taking 25mcg of Levo, started in December. Not sure why there is no T4 result. My TSH has come down slightly since December test.

You are undermedicated to have TSH 4.08 and should request a Levothyroxine dose increase. The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 0.2 - 1.0 with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted. Read Treatment Options in thyroiduk.org.uk/tuk/about_... Email dionne.fulcher@thyroiduk.org if you would like a copy of the Pulse article to show your GP.
VitD 33 is considerably below range. Has your GP offered treatment?
Ferritin and iron results are good.
Eosinophil count is mildly elevated. The rest of the FBC is within range (normal) so it's unlikely to be significant but you can Google "Eosinophil high" to check for possible causes.
Folate could be higher. Eating leafy green veg increases folate and you could add a B Complex vitamin which has a little folic acid or methylfolate, particularly if you supplement methylcobalamin.
Thanks so much for replying. Well remembered on the Hashimoto’s and that I have already gone gluten free.
I have spoken to the doctors and they’ve said I need to have a vitamin D retest. I asked them to test T4 and my antibodies again. The doctor said that she wouldn’t increase my Levo because my T4 was 17 when it was tested in December and she doesn’t want this to go too much higher, she said this is irrespective of the TSH... that they are now claiming is normal as it’s under 5!!!
She also requested a test that is something to do with my bones and another one that I didn’t understand what she said was being tested. I will ask when I go to get bloods done on Wednesday.
So frustrated that I’m back to being told your TSH is normal 🙁
Suggest you see a recommended thyroid specialist of the Thyroid UK list then
Or print out the link I gave you that's Leeds endocrinologist specialist thyroid department official guidelines - clearly states if a TSH is over 2 you are under medicated
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)."
You can obtain a copy of the articles from Thyroid UK email print it and highlight question 6 to show your doctor please email Dionne at
tukadmin@thyroiduk.org
Plus the list of recommended thyroid specialists
Professor Toft recent article saying, T3 may be necessary for many otherwise we need high FT4 and suppressed TSH in order to have high enough FT3 (the only active hormone)
If you start or are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results
