elevated b12 levels?

[Guest guest]

I am working with a mom locally that just had plasma levels of b12 checked on a

treatment naive 6 year old boy and they are elevated. I have never heard of

this but I thought some of you may have thoughts and suggestions?

I am scraping my memory here, but does this indicate that b12 isn't getting a

methyl donor and therefore accumulating? Or GI dysfunction perhaps?

Thanks,
