Could a simple blood test catch hidden diabetes in late pregnancy?
NCT ID NCT07776314
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial asks whether screening pregnant women for gestational diabetes at 32-34 weeks—later than usual—can improve outcomes. Women who previously tested negative or were never screened will get a fasting blood glucose test. The study will track complications like NICU admissions, large babies, and high blood pressure to see if later screening helps.

- Active substance
- Fasting blood glucose screening test
- What this could lead to
- If screening catches late-onset gestational diabetes, it could lead to earlier treatment and fewer complications for mothers and babies.
- What could go wrong
- The trial is small and early, and the benefits of screening are not yet proven. False positives could cause unnecessary worry or interventions.
