The prevalence of cobalamin deficiency has ranged from 3% to 29%.1- 3 Subtle cobalamin deficiency is defined as metabolic evidence of cobalamin deficiency, such as elevated serum or urine methylmalonate levels, or abnormal findings on a deoxyuridine suppression test, or the absence of neurological symptoms or megaloblastic anemia.4 The prevalence of subtle cobalamin deficiency is unknown, but in one elderly population was 39%.1 Concerns have been raised regarding the initiation of widespread folate supplementation because it might obscure the hematologic effects of cobalamin deficiency and facilitate the progression of neuropsychiatric damage.4- 5
