Summary

A screening program effectively identified thalassemia minor and iron deficiency in obstetric patients. Early detection prevents anemia and ensures better maternal health outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Medical Screening

Background:

  • Thalassemia minor and iron deficiency anemia are common conditions in pregnancy.
  • Early detection is crucial for optimal maternal and fetal health.
  • Screening protocols can improve diagnostic rates.

Purpose of the Study:

  • To evaluate the effectiveness of a screening program for thalassemia minor in obstetric patients.
  • To assess the prevalence of thalassemia minor and iron deficiency in this population.
  • To determine the utility of mean corpuscular volume (MCV) as an initial screening parameter.

Main Methods:

  • Screening of 918 obstetric patients using erythrocyte mean corpuscular volume (MCV) < 80 fL.
  • Further evaluation included serum iron, total iron binding capacity, hemoglobin electrophoresis, and iron replacement trials.
  • Diagnosis of thalassemia minor was confirmed by persistent microcytosis after excluding iron deficiency.

Main Results:

  • Twenty-six women (2.8%) had initial MCV < 80 fL.
  • Three cases of unsuspected thalassemia minor (one alpha, two beta) were detected.
  • Sixteen of 17 iron deficiency cases were identified before significant anemia developed.

Conclusions:

  • A simple screening program effectively identifies pregnant women with unrecognized thalassemia minor.
  • The program also detects iron deficiency before anemia becomes clinically significant.
  • This screening approach improves early diagnosis and management in obstetric care.
