Can a blood test or eye scan predict pregnancy risks?
NCT ID NCT07669935
First seen Jun 27, 2026 · Last updated Jun 30, 2026 · Updated 2 times
Summary
This study will follow 5,500 first-time pregnant women to see if blood tests and eye scans can predict complications like preeclampsia, fetal growth restriction, and gestational diabetes. Researchers will collect samples and images at different points during pregnancy and compare them to health outcomes. The goal is to develop better ways to identify high-risk pregnancies early.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to simple tests that predict serious pregnancy complications early, helping doctors manage risks and improve outcomes for mothers and babies.
- What could go wrong
- This is an observational study, not a treatment trial. It may not find reliable biomarkers, and any tests developed would need further validation before use in clinics.
