It's virtually impossible to get GP (or standard endocrinologist) to test FT3, hence thousands on here forced to test privately
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 Thyroid antibodies are raised, or if inadequately treated
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and fasting. Do not take Levothyroxine dose in the 24 hours prior to test, delay and take 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)
Is this how you do your tests?
Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies or all 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 antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).
About 90% of all 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 .
Then the cause of your hypothyroidism is Hashimoto's, also more likely called autoimmune thyroid disease by your GP
Essential to test vitamin D, folate, ferritin and B12. Always get actual results and ranges. Post results when you have them, members can advise
Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels
Low vitamin levels affect Thyroid hormone working
Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten. Dairy is second most common.
According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps, sometimes significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)
Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies
Ideally ask GP for coeliac blood test first or buy online for under £20, just to rule it out
But NDT doesn't suit everyone. Lots of us prefer T3 in combination with Levothyroxine. It's very flexible in being able to make small adjustments in dose of T3 or Levothyroxine

My GP has a total block when it comes to this. He says I’m healthy and in range and won’t even sign off a private blood test via our hospital which I don’t understand because I would pay for it.
Tbh I do feel well. I’ve lost weight, eat healthily and walk the beaches daily but I want to do the best for me.
Looking at the cost of these private endos and specialists I’ve decided to go via Medicheck with a home test - thyroid and vitamins.
Good morning, I have had my ultra vit test results and posted on the forum last week. My t3 is 4.69 (3.1-6.8) t4 is 20.01 (12-22), tsh 0.139 (0.27-4.2). So obviously getting plenty of t4 but not converting.
I’m working on optimising vitamins, gluten soy and dairy free, don’t drink or smoke (never have), exercise - long walks, eating healthy foods, therefore doing what I can as far as I know to help myself.
I’ve seen the article on D102 on the Thyroid Uk website and I’d like to have it done for peace of mind and to eliminate the guesswork.
But getting Thyroid hormones optimal, if test positive for DIO2, must be a step in the right direction
Certainly my brain fog improved significantly with correct vitamin levels, and futher slow steady improvement once strictly gluten free diet. Icing on the cake for brain function was addition of T3. (Plus I was virtually physically immobile on just Levothyroxine)
Some CCG's are currently refusing to prescribe (directly against guidelines) regardless of clinical need
CCG's are not entitled to override national guidelines, so a robust challenge is frequently required if NHS endocrinologist does agree clinical need for Liothyronine
