Abstract
Aim of the work
To assess STfRs levels in newborns, healthy children with iron deficiency anemia and to observe its response to iron supplementation. This was to evaluate the performance of STfRs and STfRs: S.F in the assessment of iron deficiency in infants and to analyze age-related changes in both variables.
Conclusion
We conclude that TfR and TfR: SF is associated with age related changes.
TfR and TfR: SF appears to be better indicators of iron deficiency in infants than serum ferritin.
A high STfRs concentration in children especially in infants is a response to physiologically low iron stores and erythropietic activity.
Thus we now have an additional useful marker in addition to old and newer ones, in the clinical work up of patients with suspected iron deficiency or erythroid hyperproliferative disorders.
