TSH 1.18 and T4 12.1 that’s what’s writtten on paper but have been told I have an under active thyroid at 8.3, although within the range of 8 to 20 ?However is low and suggest I go on thyroxine?
Any advice or thought.... I am going through menopause and struggling with HRT patches not absorbing. Sweats, hot flushes, low mood and anxiety
Suggest you get vitamin D, folate, ferritin and B12 tested too.
Also both TPO and TG antibodies for autoimmune thyroid disease also called Hashimoto's
So for full Thyroid evaluation you need TSH, FT4, TT4, FT3 plus TPO and TG thyroid antibodies. Plus vitamin D, folate, ferritin and B12.
Essential to test thyroid antibodies, FT3 and FT4, plus vitamins
Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

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. Low vitamins are especially common with Hashimoto's. Food intolerances too, especially gluten. So it's important to get antibodies tested.
Do you have the range for the FT4? And can you tell us what was 8.3? A bit difficult to give any advice or thoughts without all the information. 
The info I have is
free T4 at 12.1 and TSH at 1.18
Testosterone at less than 0.5
SHBG 39
Oestradiol 75 PMI/l
Vitamin D at 85.7
Although most of this relates to menopause I was also told my thyroid was 8.3 and I should get my GP to prescribe thyroxine.
At the moment that’s all the info I have but appreciate it’s not much for you to go on
No, it's not a lot to go on. A TSH of 1.18 is fine, but if it was 8, that's hypo. And, if your TSH has gone from 8 to 1.18, you need your antibodies tested.
I can't say anything about the FT4 without knowing the range.
Never take your doctor's word for nutrients being 'OK'. He wouldn't know if they were or they weren't! Get the numbers - results and ranges.
Folate, ferritin and B12 all ok apparently
Haven’t had any other tests for TT4, FT3,FT4,TPO or TG ... haven’t been mentioned.
OK is not a number. You needed actual numbers and the lab ranges for your results. Never believe anyone who says "fine" or "OK" (it usually isn't), you need to know and it is your right to have your results
