Vitamin B12 Deficiency and Early Rise in Mean Corpuscular Volume

Charles A. Hall, MD

JAMA. 1981;245(11):1144-1146.


Abstract

An increase in the mean corpuscular volume (MCV), while not diagnostic of vitamin B12 or folate deficiency, is a valuable, readily available screening test. I discuss six instances where an increased MCV was recorded months prior to diagnosis and could, if noted, have led to an earlier diagnosis.
