High B12 - what does it mean?

[ZeilaJee]

I have had consistently high, and getting higher, B12 readings in my blood tests for a year now. Apparently high B12 is associated with inflammation and possibly liver problems - how might it be related to Hashi's hypo please? I don't take B12 supplements though I do take an (occasional now) b complex (Igennus). The reading are

Sept 2020 578 pmol/L (range 145 - 569)

Feb 2021 856 pmol/L ditto

Nov 2022 865 " ditto

Mar 2023 896 " (don't know range - tested by GP surgery).

My latest thyroid results are

TSH 0.07 (don't know other info/range - tested by GP surgery)

T3 4.8 ditto

T4 12.7 ditto

I asked specifically for FT3 and FT4 (and they weren't even going to test the T3) but it doesn't look as if I got them. These are yesterday's results.

Thanks - hope you can reassure!

Vitamin B complex contains B12

Those results look like ft4 and FT3

You are legally entitled to ranges as results are meaningless without them

Get printed copies of results from GP receptionist

Was test early morning and last dose Levothyroxine 24 hours before test

Test was 9.20 am with your advice followed re dosage of NDT split 24 hours and 12 hours before testing. No breakfast or drinks other than water beforehand. Thank you for your response.

I will get ranges but as takes a long time waiting on phone may not be v quick

[ZeilaJee in reply to SlowDragon]

I haven't taken B complex for at least 3 months

[SlowDragon Administrator in reply to ZeilaJee]

Takes many months for B12 levels to reduce

What are your most recent folate, vitamin D and ferritin results

[ZeilaJee]
