Can your elevated b 12 be a false positive and you really have a deficiency of b12. I think I saw an article about this but cannot find it now.. need help to find it

Interested in more discussions like this? Go to the Digestive Health Support Group.

It is, but I understand it to be pretty rare:

“ Elevated serum B12 levels may also be associated with a functional deficiency of the vitamin. Functional deficiency has been described despite high B12 concentrations and is due to a failure of cellular uptake or intracellular processing, trafficking or utilization.”,intracellular%20processing%2C%20trafficking%20or%20utilization.

Do you believe you have symptoms of B12 deficiency? My B12 was elevated and it was because I was taking Liquid IV, the electrolyte supplement. Usually there’s something you’re consuming pushing the level up.

Is your doctor concerned about vitamin B levels? What symptoms or concerns led to your question?
