RESUMO

We measured cord blood zinc protoporphyrin/heme (ZnPP/H) and plasma ferritin in healthy African-American and Hispanic newborns, matched by gestation with Caucasian newborns. In these at-risk minorities, cord ZnPP/H was higher and plasma ferritin lower, supporting the feasibility of screening newborns at-risk for iron deficiency at birth.
