Outcome Measures
Primary Outcomes (1)
Determine if there is glucose value after the 50-gram oral GTT that can be used to diagnose gestational diabetes
The primary outcome will be the 50-gram glucose results for patients that were diagnosed with gestational diabetes by a 100-gram glucose challenge.
through study completion, up to 18 months
Eligibility Criteria

You may qualify if:
- Singleton pregnancies in which a 3-hour, 100-gram glucose test was completed and failed after 24-weeks' gestation.
You may not qualify if:
- Pregnancies with multiple gestations, glucose tests prior to 24 weeks', or those with incomplete 50-gram or 100-gram screening records.
