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 money off offers.
All thyroid tests should ideally be done as early as possible in morning and fasting. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)
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
Yes , I saw the GP yesterday and had to chase my previous results she wanted to see in her words " A drop" in levels or if that is your normal" , and as ft4 has not changed in that time thats obviously my " normal".
Those results, if unmedicated, suggest secondary or central hypo as free T4 is very low in range and TSH is not high (with such low free T4 you'd expect TSH over the top of the range) - you need an endo referral as GPs are not trained to recognize or treat it.
