title: [The role of plasma ferritin determination in screening for iron deficiency. Apropos of a study in 2 groups of children of different socioeconomic background].
abstract: A study of 72 children, aged between 6 and 24 months who came from socio-economic background has shown: plasma ferritin levels decrease gradually between 3 weeks and 6 months of age. Between 6 months and two years, levels reach a plateau but the values are lower than those of adults. The mean ferritin level is lower at any given age in children with iron deficiency but plasma ferritin levels may be in the normal range although there is obvious iron deficiency. By contrast the saturation of siderophillin can be used to determine inadequate supplies of iron to the marrow. The frequency of iron dificiency in infants under 1 year was similar in the two socio-economic groups. However between 1 and 2 years no iron deficiency was detected in the children under regular supervision but all the infants who were socially disadvantaged became iron-deficient demonstrating the need for regular iron supplements.
