CRP is an inflammation marker, yours is nice and low so that's all good.
TSH H 9.97 (0.27 - 4.20). mIU/L.
T4 Total 78.4 (64.5 - 142.0) nmol/L
Free T4 13.0 (12-22). nmol/L
Free T3 4.24 (3.1-6.8) .pmol/L
Most doctors wait until TSH reaches 10 before they will diagnose Hypothyroidism. With such a low FT4 and being just 0.03 from the magic 10, I would hope that you get a diagnosis of primary hypothyroidism now.
Anti thyroid peroxidase abs 22.5 (<34) kIU/L
Anti thyroglobulin abs H 978 (<115) kU//L
Your TG antibodies are extremely high, this confirms autoimmune thyroid disease aka Hashimoto's. This, along with your high TSH and low FT4, means you really should be diagnosed and treated now.
Hashimoto's is where antibodies attack the thyroid and gradually destroy it. Read about Hashi's here:
You can help reduce the antibodies by adopting a strict gluten free diet. Gluten contains gliadin which is a protein thought to trigger antibody attacks. Read about the gluten/thyroid connection here
Supplementing with selenium L-selenomethionine 200mcg daily and keeping TSH suppressed also help reduce antibodies.
Ferritin 23.7 (20 -150). Aug/L.
This is dreadfully low, see your GP about this. No thyroid hormone can work with ferritin at this level, neither our own nor replacement. It needs to be at least 70, with half way through range recommended, and for females 100-130 is apparently best.
You might want to ask your GP to do an iron panel, full blood count and haemoglobin test to see if you have iron deficiency anaemia.
If you are given iron tablets then take each tablet with 1000mg Vit C to aid absorption and help prevent constipation. If you are prescribed Levo then take it four hours away, and for any other medication and supplements leave two hours as it affects absorption.
Eating liver regularly, no more than 200g a week, will help raise ferritin.
Vitamin D (25OH). L 22 (deficient <25) (insuffient 25 -50) (consider reducing dose >175) nmol/L
Recommended level is 100-150nmol/L.
Ask your GP to check the Vit D Deficiency guidelines for your area. They will be very similar to the NICE Clinical Knowledge Summary which states
"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 maintenance treatment of about 800 IU a day. Higher doses of up to 2000 IU 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 regimens 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)."
So you need loading doses followed by a maintenance dose for life.
Please come back and tell us what your GP prescribes.
There are important cofactors needed when taking D3 which your GP won't know about because they're not taught nutrition, read about them here
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, four hours away from Levo if prescribed.
Magnesium comes in different forms, check here to see which would suit you best and as it's calming it's best taken in the evening, four hours away from Levo if prescribed
B12 274 (deficient <140) (insufficient 140-250) (consider reducing dose >725) pmol/L
Serum Folate 10.74 (8.83-60.8). Nmol/L
These work together. B12 under 500 can cause neurological problems. Recommended level is very top of the range, even 900-1000. You can buy some sublingual methylcobalamin lozenges 5000mcg and take one daily. Finish the bottle then buy the 1000mcg dose and take one daily. Solgar and Jarrow's are popular.
Folate should be at least half way through it's range. Whilst taking B12 we also need a B Complex to balance all the B vitamins. If you buy one with 400mcg methylfolate that will help raise your folate level. Look at Thorne Basic B (one capsule daily) and Metabolics B Complex (two capsules daily and contains no fillers).
