    Area of Science:

    • Perinatal Medicine
    • Biochemistry
    • Neonatology

    Background:

    • Maternal serum concentrations of calcium, magnesium, phosphorus, and albumin are vital during pregnancy.
    • Understanding these levels in maternal, cord, and neonatal blood is crucial for perinatal health.

    Purpose of the Study:

    • To investigate the relationship between maternal, cord, and neonatal serum levels of key minerals and albumin.
    • To elucidate the role of maternal serum ionic calcium in perinatal calcium homeostasis.

    Main Methods:

    • Serum samples were collected from 115 near-term deliveries (maternal, cord, and neonatal at 24 hours).
    • Measurements included total and ionic calcium, magnesium, phosphorus, and albumin.
    • Statistical analysis was performed to assess correlations and differences between groups.

    Main Results:

    • Cord blood levels of all measured components were higher than maternal levels and correlated significantly.
    • Maternal serum ionic calcium concentration was found to be important for perinatal calcium homeostasis.
    • Neonatal serum levels at 24 hours correlated significantly with cord blood levels, with notable changes in calcium and phosphorus concentrations post-delivery.

    Conclusions:

    • Maternal serum ionic calcium concentration is a key determinant of normal perinatal calcium homeostasis.
    • Significant correlations exist between maternal, cord, and neonatal levels, underscoring the transfer and regulation of these substances.
    • Postpartum changes in neonatal serum calcium and phosphorus levels indicate physiological adjustments after birth.
