No : Not bad. Usually caused by vitamin supplementation. No need to bring them down.

Needs evaluation: High B12 & folate (folic acid) is not dangerous per se (these vits. Have no known toxicity)& may not be serious, but high B12 may paradoxically be a sign of B12 deficiency & may also be caused by acute or chronic liver disease or leukemia, so deserves further evaluation-see http://healthyeating.Sfgate.Com/high-vitamin-b12-serum-levels-6037.Html high folate (folic acid) may be a sign of B12 deficiency or blind loop syndrome.

A 21-year-old female asked:

What would cause elevated B12 and folate (folic acid) levels?

Stop worrying: We see these from time to time. They are no cause for concern. Reference ranges are set for the vast majority of people. Just be happy. Elevated B12 has some arcane significance in hematology but it does not apply to healthy people. Just be glad.
