I would appreciate if someone helps me to read my blood results. My thyroidectomy was done 11 years ago due to Graves disease and I was treated after only with T4. Last 6 months I am using ERFA NDT 2x60mcg a day..The test was done in Finland, so the lab range can vary. The last dose of NDT was taken 24hrs before the blood test.
TSH ( 0.4-4.5 mU/l).......... 0.48
FT4 (11-21 pmol/l) ........... 11.6
FT3 (3.5-6.5pmol/l)............ 3.9
TPOAb (<60 kU/l) ………... 28
TyglAb (<4 kU/l ) …………. 3
D3 – 25 (>50 nmol/l)……….. 59
Ferritin (13-150 ug/l)……….. 56
B12-TC2 (>35 pmol/l)………. 97.2
Folate (208-972 nmol/l)…….. 1172
Selenium (0.64-1.52 umol/l)… 1.27
Magnesium (0.71-0.94mmol/l) 0.78
CRP (<8 mg/l) ……….. 5
HbA1c (20-42 mmol/mol) 32
Insulin (2-20 mU/l)……….. 4.5
Thank you.

The time gap between last dose of NDT and blood draw should be 8-12 hours (because of the T3 element in NDT), so you have false low FT3 and FT4 may be lower than normal too due to you leaving 24 hours.
D3: 59 (>50 nmol/l) = 23.6ng/ml
This is too low. The Vit D Council recommends a level of 125nmol/L [50ng/ml] and the Vit D Society recommends a level between 100-150nmol/L [40-60ng/ml].
For your current level, the Vit D Council recommends supplementing with 3,700iu D3 daily (nearest is 4,000iu). Once you've reached the recommended level 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.
There are important cofactors needed when taking D3 as recommended by the Vit D Council -
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.
Check out the other cofactors too (some of which can be obtained from food).
Ferritin: 56 (13-150 ug/l)
For thyroid hormone to work (that's our own as well as replacement hormone) it's said that 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, also liver pate, black pudding, and including lots of iron rich foods in your diet
Well yes, I was also thinking the same about that low FT3 and FT4. But unfortunately my GP from UK told me to have this 24hrs gap between the blood test, so I was expecting these results. I will better do it again with only 8-12hrs gap.
Good to know that I should raise my D3 levels too because I wasn't supplementing almost anything recently. The Folate levels must be so high because I'm eating goose liver 2x a week or then something else. I don't supplement B-complex either.
