In August after a GP blood test my thyroxine was reduced from 150mcg to 125mcg daily. I decided on a private blood test but have had to wait for a nurse appointment, finger pricks don't work!
Here are the results:
TSH 0.11mIU/L (0.27-4.2)
Free T3 3.3pmol/L (3.1-6.8)
Free Thyroxine 18.1pmol/L (12-22)
Ferritin 129ug/L (30-650)
Folate 11.5nmol/L (8.83 -60.8)
Vitamin D 80nmol/L (50-250)
Active B12 120pmol/L (37.5-188)
I have been taking 25ug D3 every day but Vitamin D seems lowish.
And the comments with the results say 'TSH is low which suggests levothyroxine may be too high' which could lead to osteoporosis and I should consider asking my GP for a bone density scan. No comment was made about T3!

I'm female, 72 years old so post menopause. It is a Medichecks test. I don't take Vitamin B complex. I'm concerned most about the thought of osteoporosis. Over the years most blood tests have shown low-ish TSH which my previous GP said was OK. Sadly my new GP is a numbers man.
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)
Currently Thorne is cheapest on eBay at £18
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
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement - eg Jarrow methyl folate 400mcg
This is a Medichecks test and the lab used to process the tests is INUVI.
I have a very hard time taking their ferritin range seriously, in all the years I've been commenting on results here I have never, ever, seen a ferritin range go above 400 and that's the male range which goes higher than the female range. The female range is usually 13-150 and some labs (eg my GP lab) uses 15-300 as a general range for both males and females (pre and post-menopausal).
My personal thoughts are to ignore this range altogether. The unit of measurement is the same as all the other ranges - ug/L - and my interpretation (with the caveat that I am not medically trained) is that some experts say that the optimal level for thyroid function is 90-110ug/L so I can't see anything wrong with that ferritin result.
If you are interested you could contact Medichecks for an explanation, ask why the INUVI range is so wide when the range given when Eurofins County Pathology or The Doctor's Laboratory process their ferritin tests the range is 13-150 with the same unit of measurement.
I posted here last week re the Medichecks ferritin range from the Inuvi lab going upto 650, and been contacting them as my ferritin was now 6% thru the range after two years of really trying to increase it. I am now waiting for the third reply back; they are getting a medic.to comment, so perhaps they will at last realise this range is ridiculous. I might be struggling at bottom of range, but do wonder how ill might those be at 100%!
Once you Improve level, very likely you will need on going maintenance dose to keep it there.
Vitamin D tablets or gels must be minimum 4 hours away from levothyroxine and best taken with evening meal (as likely the meal with highest fat content j
However Vitamin D mouth spray by Better You is very effective as it avoids poor gut function. Can be taken an hour away from levothyroxine
There’s a version made that also contains vitamin K2 Mk7.
