Hi its me again

Ive had my thyroid removed for over 8 years

I was on 175mcg of levothyroxine mon to Fri and 150mcg sat & sun

However my stroke Specialist has said I need to reduce my levothyroxine to 150mcg everyday has my t4 level is still up at 21

Does anyone know the range for t4 please

There is no universal range so you need the range that comes with your own test, no other range will be relevant as they vary from lab to lab.

If your GP did the test then ask the receptionist for a print out of your results and the range will be on there. If the test was done at the hospital you could either request a copy of your results or ring the path lab and ask them for the range.

Do you always get bloods tested as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

If you take levothyroxine BEFORE test, it gives false high Ft4 results

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

Ask GP to test vitamin levels

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 .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

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
