I recently had private blood tests done and the thyroid results were:
TSH 0.08 (range 0.27-4.2)
Free T3 5.02 (range 3.1-6.8)
Free T4 11.2 (range 12-22)
I take 75 mcg T4 per day plus 15 mcg T3 liothyronine per day and followed the suggested testing rules from here. I still have a lot of symptoms including headaches, brain fog, bloating/gas, fatigue, dry eyes and problems sleeping. I also have 3 monthly B12 injections so it's difficult to know which is causing the symptoms. My vitamin D level was 60 so I'm taking vitamin D with vitamin K and also take magnesium.
I was wondering if I should ask my GP if I can have an increase in T4 and would be grateful for any advice/views on my results.

Was test done early morning, around 9am and last dose levothyroxine 24 hours before test
Last 5mcg dose T3 approx 8-12 hours before test
many members on levothyroxine plus small dose T3 find they need both Ft4 and Ft3 at approx 70% through range
Vitamin D needs improving to at least around 80nmol and around 100nmol maybe better
What were folate, ferritin results
Do you take daily vitamin B complex as well
As you have B12 injections it’s recommended also to supplement a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.
This can help keep all B vitamins in balance and will help maintain B12 levels between injections
If 3 months is too long between injections you can request 2 monthly time scale
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule)
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
Thank you for all the information. The test was done per your guidelines and ferritin was 115 ( 13-150) and folate 10.34 (greater than 3.89). I am now taking a B12/folate supplement, magnesium and vitamin D with K spray. I stopped taking vitamin D in the summer but it seems that I need to take it all the time. I haven't had antibodies tested recently but in 2018 thyroglobulin was 58.7 (0.00-115.00) and thyroid peroxide antibodies 27.1 (0.00-34.00) but the consultant who I saw said I had hashimoto's. I've never had an ultrasound scan. I have a fairly regular diet not vegan or vegetarian but do try and eat lots of veg. I'm not gluten or dairy free. I've had a test for celiac and also gluten intolerance, both were negative. I tend to buy lactose free milk as my daughter discovered she is lactose intolerant. I do use eye drops in the winter, my eyes seem to be fine during the summer. I will try and make an appointment to see the GP and ask for more frequent B12 jabs as I do get symptoms before the 3 months is up such as a sore tongue and also try for a higher dose of T4 to see if that helps. Once again thank you all your help and links.
