This thyroid test result appears ok but I have a lot of hypothyroid -related symptoms
Many thanks

Are you already on levothyroxine?
Or trying to get diagnosed?
If on levothyroxine your dose is likely too low
The aim of Levothyroxine is to increase the dose slowly in 25mcg steps upwards until TSH is under 2 (many need TSH significantly under one) and most important is that FT4 is in top third of range and FT3 at least half way through range
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 and thyroid antibodies
You may need to get full Thyroid testing privately as NHS refuses to test TG antibodies if TPO antibodies are negative
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, best not mentioned to GP or phlebotomist)
Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

For thyroid including antibodies and vitamins
Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random
If you can get GP to test vitamins and antibodies then cheapest option for just TSH, FT4 and FT3 £29 (via NHS private service )

If antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).
About 90% of all primary hypothyroidism in Uk is due to Hashimoto's.
Low vitamins are especially common with Hashimoto's. Food intolerances are very common too, especially gluten.
So it's important to get TPO and TG thyroid antibodies tested at least once .

So sorry I omitted to say that I am not on thyroid medication.
Well you still need full thyroid and vitamin testing
You may find you have high thyroid antibodies and/or low vitamin levels
Your Ft4 is low in range and Ft3 is low ....but TSH isn’t high enough for doctors to say hypothyroid
But vitamins may be very low and improving levels frequently improves symptoms
Thankyou for responding so fully to my previous post with thyroid test
These were full blood results as at Jan 2020. Again U cant see anything pointing to an issue but if it excludes thyroid probs (even though all my symptoms ape hypothyroid) it is a step towards a diagnosis
Thanks in advance for looking at these

Serum total 25-hydroxy vitamin D level 87 nmol/L Vitamin D is seasonal but levels should be >75 nmol/L at all times. Levels 50-75 are probably suboptimal,
long term may lead to clinical effects. Consider safe
sun exposure, diet, supplement. Levels 25-50 indicate deficiency, supplementation is indicated. Levels <25 suggest severe deficiency-may need pharmacological preparations- in which case serum calcium should be checked after 1 month. Toxic levels of vitamin D are
not well defined but advise check serum calcium if
25 OH vitamin D exceeds 300 nmol/L and consider dose reduction if appropriate.
