T4 29.6 help

[Sleepy101]

Hi these are my latest results. No one is meeting with me to tell me if this is OK or not. I have thyroid cancer just about to have RAI. Is the t4 not a bit high? Please help me

T4 29.6

Tsh 0.01 suppression

[jimh111]

High doses of liothyronine are prescribed to keep TSH low. This is because TSH stimulates the thyroid and can stimulate the cancer. However, your fT4 is high and there might be scope to reduce your levothyroxine a little. Another consideration is that T4 itself promotes cancer and so it is undesirable to have a very high fT4. This last point isn't well known, it comes from fairly recent research.

Thank you. I wish that the consultants read latest studies. My consultant is new and said I won't have hashimotos anymore because I don't have a thyroid

Without a thyroid your Hashimoto’s may decline over time and of course it can no longer affect your thyroid.

I forgot to mention it is important to keep TSH suppressed at least until your thyroid is remover / ablated. I would follow the advice of your oncologist as regards levothyroxine dose and Gary and get some liothyronine prescribed as you will probably do better on it and it will allow TSH suppression with more normal fT4 levels.

Are you on levothyroxine?

If yes, how much

Do you always get same brand levothyroxine at each prescription

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

Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested.

Very important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

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

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
