Thyroid function test results

[Sotonowl]

Any help appreciated guys, they look normal enough to me but I understand it isn't that simple.

Plasma Free T4 13.1 pmol/L ( 7.7 - 15.1)

Plasma TSH 3.91 mu/L (0.34 - 5.6)

Are you on levothyroxine?

If yes, how much and do you always get same brand levothyroxine

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

What vitamin supplements are you currently taking

How do you feel?

[Sotonowl in reply to SlowDragon]

Thanks for the reply. I'm not on any Levothyroxine. Test was done 1.5 hours after rising with nothing to eat or drink.

I was taking Vitamin D3 and Turmeric previous to the test although I have now added quercitin and Diamine Oxydase.

TSH is higher than average healthy population....but not high enough to get diagnosed

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12

Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies

When were vitamin D, folate, ferritin and B12 last tested?

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 thyroid antibodies or all relevant vitamins
