TL;DR
Age-related changes in laboratory measurements, such as those described herein, must be taken into consideration in order to optimize the identification of individuals with anemia and iron deficiency.
Abstract
Laboratory results from the Second National Health and Nutrition Examination Survey (NHANES II) were used to define age-related changes in laboratory values that are related to the diagnosis of anemia and iron deficiency. Analyses included Hb, hematocrit, red blood cell count, red cell indices, iron, total iron-binding capacity, transferrin saturation, and erythrocyte protoporphyrin. Computation of median values and 95% ranges by age and sex for each laboratory test were performed on 15,093 subjects between 1 and 74 yr of age who had complete laboratory data on venous blood, after excluding those subjects with an abnormality in one or more of three other laboratory tests. Age-related changes in laboratory measurements, such as those described herein, must be taken into consideration in order to optimize the identification of individuals with anemia and iron deficiency.

The prevalence of iron-deficiency anemia among infants and children in the United States is now relatively low, but iron deficiency remains the leading cause of anemia.

The percentile curves were derived from several populations of non-indigent white children who lived near sea level and should be particularly applicable to the diagnosis and screening of iron deficiency and thalassemia minor.

Using a combination of this new protoporphyrin assay together with either the determination of blood lead, the presence of increased eythrocytic osmotic resistance or the measurement of δ-aminolevulinic acid dehydratase permits a distinction to be made between acute and chronic lead poisoning and/or iron deficiency anemia.

Serial analysis of individual infant's values indicated that the red cell measurement at 4 months of age are, to some extent, predictive of the level of subsequent values within the normal range.

This work investigated the developmental changes in serum iron, total iron-binding capacity, and transferrin saturation in infancy to establish the lower limits of normal values under conditions in which iron deficiency was prevented by dietary supplementation, and its absence confirmed by laboratory tests.

It is concluded that in children between the ages of 0.5 and 12 years, a transferrin saturation of less than 16% constitutes good evidence of iron deficiency only in conjuction with anemia and low mean corpuscular volume.

Age‐sex specific reference values and frequency distribution of erythrocyte parameters were derived from a representative sample of a natural population unselected as to disease and are presented as percentile distributions by age and sex rather than as the more frequently used normal distribution.

Findings suggest that the rise in serum-T.I.C.B.C., serum-iron, and serum total iron-binding capacity in the group using oral contraceptives were strikingly elevated, and may be partly due to a response to circulating œstrogens and/or progesterone.

There is a strong inverse association between MCV and red blood cell count, which may be part of a mechanism to ensure constant oxygen carrying capacity and is not seen in women not on oral contraceptives.
