Diagnosis of Gestational Diabetes Based on a 50-gram Glucose Challenge

The aim of this study is to determine a 1-hour glucose tolerance test (GTT) value at which the diagnosis of gestational diabetes can be made without undergoing a 3-hour test.

Retrospective chart review to ascertain the 50-gram glucose screen values in pregnant women at Methodist Dallas Medical Center from April 2020 to April 2023 who failed the 100-gram glucose load.

Inclusion Criteria:

• Singleton pregnancies in which a 3-hour, 100-gram glucose test was completed and failed after 24-weeks' gestation.

Exclusion Criteria:

• Pregnancies with multiple gestations, glucose tests prior to 24 weeks', or those with incomplete 50-gram or 100-gram screening records.
