Magnesium levels in amniotic fluid were measured in 150 pregnant women. The average magnesium concentration found was 1.7 mg/dl, providing insights into prenatal nutrient levels.

Area of Science:

  • Obstetrics and Gynecology
  • Clinical Chemistry
  • Prenatal Diagnostics

Background:

  • Magnesium is an essential mineral crucial for fetal development.
  • Monitoring amniotic fluid composition offers insights into the intrauterine environment.
  • Understanding magnesium levels during pregnancy is important for maternal and fetal health.

Purpose of the Study:

  • To determine the concentration of magnesium in amniotic fluid.
  • To establish reference values for magnesium in amniotic fluid across different gestational ages.
  • To assess the utility of a direct colorimetric method for this analysis.

Main Methods:

  • A direct colorimetric method was employed for magnesium determination.
  • Amniotic fluid samples were collected from 150 pregnant women.

  • Samples were analyzed across a wide range of gestational ages (9-41 weeks).

    • Main Results:

    • The mean concentration of magnesium in amniotic fluid was found to be 1.7 mg/dl.
    • The standard deviation for the magnesium concentration was 0.39 mg/dl.
    • This value represents a key finding for magnesium levels in late-stage pregnancy.

    Conclusions:

    • The study establishes a mean magnesium concentration in amniotic fluid.
    • The findings provide a reference point for magnesium levels during pregnancy.
    • Direct colorimetric analysis is a viable method for assessing amniotic fluid magnesium.
