Medichecks result: B12 way too high, TSH suppressed - T4 and T3 somewhere in range? Help please?

[Josephineinamachine]

Hi all

These are my latest Medichecks results, blood test taken first thing in the morning, fasting, no vitamins for a week, previous dose of Levothyroxine morning before. I'm really surprised because I'm not feeling well and these results indicate that I should be? Except for the high Vit B result? What does this mean pls?

I do not supplement any B vitamins.

I do supplement Vit D, Vit K, Selenium, Zinc and Magnesium.

Am still tired, not sleeping well, and still these aching legs?! Brain fog. Core temp was low when I had it checked for the blood test at the hospital.

Have been on 100mg Levo for 8 weeks:

Any help please?

Ferritin 120 ug/L (Range: 13 - 150)

Folate - Serum 14.8 ug/L (Range: > 2.9)

** Vitamin B12 - Active X 201 pmol/L (Range: 25.1 - 165)

**Vitamin D 84 nmol/L (Range: 50 - 200)

Thyroid Hormones

** TSH X 0.08 (Range: 0.27 - 4.2)

Free T3 5.5 (Range: 3.1 - 6.8)

Free Thyroxine 18.0 (Range: 12 - 22)

Autoimmunity

Thyroglobulin Antibodies 49.7 (Range: 0 - 115)

**Thyroid Peroxidase Antibodies X 77.7 (Range: 0 - 34)

Thank you for your advice!

Ferritin 120 ug/L (Range: 13 - 150)

I have read that a good ferritin level for females is 100-130 so I would be thrilled if mine was 120!

Do you eat a lot of meat or eat liver/liver pate/black pudding? If you'd had some in the few days before the test this could raise your level. Also inflammation can raise ferritin, but yours is in range so personally I think it's fine.

Folate - Serum 14.8 ug/L (Range: > 2.9)

Folate is recommended to be at least half way through range, their range is 2.9-14.5 so again you might be getting folate from our diet.

** Vitamin B12 - Active X 201 pmol/L (Range: 25.1 - 165)

This is high. You could discuss with your GP if worried.

**Vitamin D 84 nmol/L (Range: 50 - 200)

Why is Vit D flagged? What did they say in their comments (if you had them).

The Vit D Society and Grassroots Health both recommend a level of 100-150nmol/L so really you could do with improving your level although technically it comes within the "sufficient/adequate" category.

How much D3 do you take?

Thyroid Hormones

** TSH X 0.08 (Range: 0.27 - 4.2)

Free T3 5.5 (Range: 3.1 - 6.8)

Free Thyroxine 18.0 (Range: 12 - 22)

I'm not feeling well and these results indicate that I should be?

Your FT4 is still only 60% through range, you probably need it higher, maybe 75% through range or even higher. You're converting T4 to T3 nicely as FT3 is 65% through range.

Autoimmunity

Thyroglobulin Antibodies 49.7 (Range: 0 - 115)

**Thyroid Peroxidase Antibodies X 77.7 (Range: 0 - 34)

Your raised TPO antibodies confirm autoimmune thyroid disease, known to patients as Hashimoto's. Did you already know this?

Thank you SeasideSusie

I do eat a high protein low carb diet, so eggs and meat every day with a lot of vegetables and salad, berries and raw nuts. I don’t take iron supplements. Could this cause the high B12 do you think? I’m worried about that. I don’t drink alcohol.

I’m due a GP discussion this week. No NHS blood test done - she said she would go by symptoms.

I’m worried that maybe my symptoms are actually due to over medication - even though I know from the forum that suppressed TSH is okay...

I have had some weird flare ups with my index finger and now have strange nodules by my finger knuckle. My aunt has RA.

I’ve looked at possible causes of high B12 and found it linked to RA. So, my quest to reduce thigh pain via adequate thyroxine may be misplaced and in fact maybe it’s something else completely.

So I don’t think I’m going to ask for an increase in Levo because I’m scared I’ll feel worse than I do already, but instead ask to be tested for RA.

Thank you

Jo

Your TSH is 0.08 and it’s not suppressed until it goes below 0.04.

[Josephineinamachine in reply to Bearo]

Thank you Bearo ! I’ve been wondering whether or not to reduce because it scared me a bit. Maybe I’ll leave it as it is then. Thank you for replying x

Maybe your symptoms are due to gluten or lactose intolerance? seeing as your thyroid levels are quite good yet your antibodies are raised? Just a thought, I’m no expert in this area x

[Josephineinamachine]

Thank you HollieBerry I don’t think so because I’m gluten free and avoid milk etc. My continued symptoms which I find difficult are pain especially in my legs. Thinking it might be something else now (as well)! Thank you for responding 😊 x

High B12 can be misleading

Suggest you try adding a vitamin B complex, one with folate in

Remember to stop taking this a week before all blood tests as contains biotin
