Newborn; Anemia, Pregnancy Anemia
Conditions
Brief summary
Erythroferrone (ERFE) is a recently identified iron-regulatory hormone that couples iron homeostasis to erythropoiesis but at this time there are no human data on this hormone in pregnant women and their neonates. The investigators hypothesize that ERFE is a sensitive biomarker of iron deficiency and anemia in pregnancy and neonates, and that it mediates the feedback mechanism to correct iron deficiency and anemia. To address this research gap, the investigators will measure ERFE in maternal serum, umbilical cord serum and placental tissue using an existing biospecimen archive.
