Overview

Evaluates the effectiveness of glucose challenge tests in detecting gestational diabetes in pregnant women, indicating its clinical usefulness.

Key Points

  • The research aims to assess the effectiveness of the glucose challenge test during early pregnancy for screening gestational diabetes mellitus.
  • 201 pregnant Japanese women underwent glucose challenge tests in early and mid-pregnancy.
  • An oral glucose tolerance test was performed 2-3 weeks after the glucose challenge test.
  • Cut-off level for GCT was set at 130 mg/dl.
  • GCT sensitivity for detecting GDM in mid-pregnancy was 100% (3/3).
  • GCT specificity for GDM detection in mid-pregnancy was 88% (174/198).
  • During early pregnancy, GCT sensitivity for GDM detection was 63% (5/8) and specificity was 84% (63/193).
