I had a recent blood test with Blue Horizon as I wanted to find out my vitamin levels. I take 100mcg Thyroxine and my Free T4 measures at the top of the range at 22.3. I take vitamin D as I am post menopausal.
My levels were
B12 300 ( 197-771)
Vitamin D 84.7 ( 75-200)
Iron 13 ( 6.0- 34.5)
Ferritin 174 ( 13-150)!
Folates 5.3 (3.9-26.8)
I would be grateful for any comments.
Thanks

Would stongly suspect your dose reduction and diagnosis of fibromyalgia are linked
B12 is too low, but not low enough for GP to be interested in testing. Supplementing sublingual B12 lozenges and also good quality vitamin B complex to keep B's in balance would help
If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results
Vitamin D, many of us find getting level around 100nmol may be better, plus magnesium and vitamin K2 as cofactors
Ferritin can be high due to autoimmune issues
If you have not had FT3 and FT4 tested together with TSH recently would suggest you get this done. Perhaps wait until improvements to vitamins are sorted .
Medichecks Thyroid or Blue Horizon - DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.
All thyroid tests should be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH and most consistent results
