Low ferritin can indicate iron deficiency anaemia. You need a full blood count and a full iron panel carried out.
For thyroid hormone to work (that's our own as well as replacement hormone) ferritin needs to be at least 70, preferably half way through range.
You can help raise your level by eating liver regularly, maximum 200g per week due to it's high Vit A content, and including lots of iron rich foods in your diet apjcn.nhri.org.tw/server/in...
As you're having B12 injections there's not much to say, other than ensure you get them on time. You can top up inbetween if you feel it necessary with either self injecting or sublingual methylcobalamin lozenges.

Diagnosed folate deficient 2016
Dec 2017 Folate 1.8 (2.5 - 19.5) Folic acid 5mg
Is your folic acid daily or weekly?
You should point out to our GP that you are still folate deficient after all this time and what does he intend to do about it? You should be checked for malabsorption and gut problems.

Diagnosed vit D deficient 2014
Vitamin D 30 (25 - 50 deficiency ) D3 800iu
Nowhere near enough D3.
You should point out to your GP that 4 years of supplementing wth 800iu and you are still deficient.
"Treat for Vitamin D deficiency if serum 25-hydroxyvitamin D (25[OH]D) levels are less than 30 nmol/L.
For the treatment of vitamin D deficiency, the recommended treatment is based on fixed loading doses of vitamin D (up to a total of about 300,000 international units [IU] given either as weekly or daily split doses, followed by lifelong maintenace treatment of about 800 IU a day. Higher doses of up to 2000IU a day, occasionally up to 4000 IU a day, may be used for certain groups of people, for example those with malabsorption disorders. Several treatment regims are available, including 50,000 IU once a week for 6 weeks (300,000 IU in total), 20,000 IU twice a week for 7 weeks (280,000 IU in total), or 4000 IU daily for 10 weeks (280,000 IU in total)."
Each Health Authority has their own guidelines but they will be very similar. Go and see your GP and ask that he treats you according to the local guidelines or this summary as your level is only 30 and prescribes the loading doses. Once these have been completed you will need a reduced amount (more than 800iu so post your new result at the time for members to suggest a dose) to bring your level up to what's recommended by the Vit D Council - which is 100-150nmol/L - and then you'll need a maintenance dose 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 City Assays vitamindtest.org.uk/
If your GP refuses the loading doses, then do it yourself with high dose D3 by following the amounts above, 300,000iu over a few weeks.
As you have Hashi's you should use an oral spray, BetterYou do a 3000iu one. You could double dose and use 6000iu daily for 2 months then retest, once you've reached the recommended level you could see if 3000iu is your maintenance dose.
Your doctor wont know, because they are not taught nutrition, but there are important cofactors needed when taking D3
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.
D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds.
Magnesium helps D3 to work and 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
Then you should push for the loading doses as mentioned above, pointing out that your level was below that in the Summary (<30) and is only just 30 now. If your GP wont give them, then just buy D3 yourself and follow advice about matching the loading doses outlined above.
Just haven't been given iron
Then as I said low ferritin can indicate iron deficiency anaemia. You need a full blood count and a full iron panel carried out so ask your GP to do these.
