Detection of vitamin B12 deficiency in older people by measuring vitamin B12 or the active fraction of vitamin B12, holotranscobalamin.

BACKGROUND Impaired vitamin B(12) function and decreased vitamin B(12) status have been associated with neurological and cognitive impairment.

Concentrations of this active component, carried on holotranscobalamin (holoTC), may be of greater relevance than total vitamin B(12). M...
