DESCRIPTION

The test measures levels of vitamin B12 in serum.

I do not usually recommend checking B12 levels in chronic fatigue syndrome patients because in most cases they benefit from B12 by injection even if the levels are "normal" (see B12 - rationale for using vitamin B12 in CFS). However, it is worth checking levels in someone who does not have CFS, but who wants to make sure that all his systems are functioning at the optimum level. This would be a useful test as part of a disease prevention screen. (See Disease prevention).

I would also prescribe B12, regardless of serum levels, in anyone with poor antioxidant status or with neurological or neuro-psychological problems.
