[Behavior of serum magnesium level during abortion]

Area of Science:

• Biochemistry
• Clinical Chemistry
• Obstetrics and Gynecology

Context:

• Magnesium is a vital electrolyte with implications in pregnancy and obstetric complications.
• Previous studies suggested a decrease in serum magnesium levels during abortions, but this requires further investigation.
• Understanding magnesium distribution in blood and erythrocytes is crucial for diagnosing and managing obstetric conditions.

Purpose:

• To investigate and compare whole blood, serum, and erythrocyte magnesium levels in healthy pregnant women and women experiencing abortions.
• To evaluate the diagnostic utility of serum magnesium levels in differentiating between normal pregnancy and abortion.
• To explore the relationship between hematocrit, serum magnesium, and erythrocyte magnesium concentrations in these populations.

Summary:

• A study involving 134 females (66 healthy pregnant, 68 abortions) measured whole blood and serum magnesium using a complexometric method.
• Serum magnesium levels were similarly depressed in both groups, contradicting previous findings of a significant decrease in abortions.
• Erythrocyte magnesium concentrations were significantly higher in women experiencing abortions compared to those with successful pregnancies, attributed to the release of immature red blood cells following blood loss.

Impact:

• Challenges the interpretation of low serum magnesium as a sole indicator for abortions.
• Highlights erythrocyte magnesium concentration as a potentially more sensitive marker in cases of abortion.
• Suggests that increased erythrocyte magnesium in abortions may be linked to reactive erythropoiesis secondary to blood loss.
