I'm really confused. I had a bluecrest work medical and as a result, it came back with a tsh level of 12. Because I didn't even realise I had an issue, my doctor retested and it gave me a tsh level of 8. So, put me on a dose of 50 Levo.
3 months later, i had another test and it showed that I had a tsh level of 0.44 (5th July) Apart from a less swollen face, didn't really notice any difference in how I felt.
Having lurked on this forum, I thought I would get my vitamins checked and went private with medi checks (1/08)
Why are they so different? I can understand slight variations. Has anyone else had this. I'm female, 51. Thoughts gratefully received.
Note all tests were on an empty stomach, early appointment before 9.30 and no Levo taken until afterwards (I take mine first thing, then wait to eat/drink coffee for an hour)
The results were
Tsh 16.8
Free thyroxine 9.78
Free t3 3.2
Thyroglobulin anti body 189
Thyroid peroxide antibodies 246
Active b12 62.1
Folate 3.23
25 oh vitamin d 65.5
Crf 1.18
Ferritin 52.1

You need to put the ranges in as ranges differ from different labs
From your antibody results It looks like you have Hashimotos which can cause flare ups and different results.On the face of it you have been caught early before more symptoms appeared.
Your NHS test must have coincided with a Hashimoto's flare.....which causes temporary high levels of thyroid hormones as thyroid cells break down
Your Medichecks test shows you need 25mcg dose increase asap and bloods will need retesting in 6-8 weeks
Dose is increased in 25mcg steps retesting 6-8 weeks later each time, until TSH is around one and FT4 towards top of range and FT3 at least half way in range
Your vitamins look low. Especially folate
Ferritin needs to be half way in range. Eating liver or liver pate once a week should help improve
Vitamin D would be better towards 100nmol. Not low enough for GP to prescribe. Just get yourself some vitamin D to self supplement
Vitamin D mouth spray by "Better You" is good as avoids poor gut function. Suggest you supplement 1000iu for 2-3 months and retest. It's trial and error what dose each person needs. Once you Improve level, very likely you will need on going maintenance dose to keep it there. Retesting twice yearly via vitamindtest.org.uk
Also read up on importance of magnesium and vitamin K2 Mk7 supplements when taking vitamin D
Your high antibodies confirm you have Hashimoto'. More commonly called autoimmune thyroid disease by GP
Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels
Low vitamin levels affect Thyroid hormone working
Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten.
According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)
Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies
OK so folate and B12 are low, but within range. (Active B12 under 70 is considered suspect)
Keep an eye on them next test. You might want to consider adding a good quality vitamin B complex, one with folate in not folic acid
But only ever make one change or add one supplement at a time
Most important is to get dose of Levothyroxine increased. Likely to need several increases. Dose should only be increased in 25mcg steps. We usually can't cope with larger increase
GP very unlikely to consider vitamins are low at all, as they are in range
Vitamin D is the most important, most of us with Hashimoto's find higher dose of vitamin D is needed. At least 80nmol, but 100nmol may be better
