Maternal and cord blood ferritin
Helvetica Paediatrica Acta
|June 1, 1982
Summary
Newborns have higher iron levels than mothers, indicating active iron transfer from mother to fetus. This iron transport is independent of fetal red blood cell production.
Area of Science:
- Perinatal Medicine
- Iron Metabolism
- Fetal Development
Background:
- Maternal-fetal iron transfer is crucial for fetal development.
- Understanding iron dynamics during pregnancy is essential for optimizing infant health outcomes.
Purpose of the Study:
- To investigate the relationship between maternal and cord blood iron parameters.
- To determine if fetal iron status correlates with erythropoiesis.
Main Methods:
- Analysis of plasma iron, transferrin saturation, and ferritin levels in 64 maternal-fetal pairs.
- Assessment of cord blood hemoglobin and red cell indices (MCV, MCH, MCHC).
Main Results:
- Cord blood iron, transferrin saturation, and ferritin levels were significantly higher than maternal levels.
- No correlation was observed between maternal and cord blood iron parameters.
- No correlation was found between cord blood ferritin and fetal hemoglobin or red cell indices.
Conclusions:
- Suggests an active, regulated iron transport mechanism from mother to fetus.
- Fetal iron acquisition appears independent of fetal erythropoiesis.
- Highlights the distinct iron regulation in the feto-maternal unit.
