You are very undermedicated with those results. When on Levo only, the aim of a treated hypo patient generally is for TSH to be 1 or lower with FT4 and FT3 in the upper part of their ranges if that is where you feel well.
If your GP's results come back similar then you need an immediate increase in your Levo of 25mcg, retest after 6-8 weeks. Continue retesting/increasing every 6-8 weeks until your levels are where they need to be for you to feel well.
As you know, your raised antibodies confirm Hashi's and you were given information about this by SlowDragon in this thread healthunlocked.com/thyroidu...
Your vitamins are good - do you supplement anything?
Did you not have the ULTRAVIT test, there is no Vit D result there.
The Vit D Council recommends a level of 125nmol/L (50ng/ml) and the Vit D Society recommends a level of 100-150nmol/L (40-60ng/ml), so it would be best to supplement to improve your level.
To reach the recommended level from your current level, the Vit D Council suggest supplementing with 3,700iu D3 daily, nearest is 4,000iu.
As you have Hashi's, for best absorption then a oral spray is recommended (eg BetterYou) or sublingual drops (eg Vitabay Organics).
When you've reached the recommended level then you'll need a maintenance dose to keep it there, which may be 2000iu daily, maybe more or less, maybe less in summer than winter, it's trial and error so it's recommended to retest once or twice a year to keep within the recommended range. You can do this with a private fingerprick blood spot test with an NHS lab which offers this test to the general public:
D3 aids absorption of calcium from food and K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as hardening of the arteries, kidney stones, etc.
D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds if taking tablets/capsules/softgels, no necessity if using an oral spray
Magnesium helps D3 to work. We need Magnesium so that the body utilises D3, it's required to convert Vit D into it's active form. So it's important we ensure we take magnesium when supplementing with D3.
Magnesium comes in different forms, check to see which would suit you best and as it's calming it's best taken in the evening, four hours away from thyroid meds if taking tablets/capsules, no necessity if using topical forms of magnesium.
You are very hypothyroid with a TSH of 12.3. Your FT4 is below range and FT4 just slightly above the bottom of the range. Due to having thyroid antibodies you have an Autoimmune Thyroid Disease, also called Hashimoto's or hashi's.
Going gluten-free can help reduce the antibodies which attack the thyroid gland (they wax and wane until you're hypo). Treatment is the same as hypothyroidism.
