New blood test could prevent dangerous delays in preeclampsia deliveries
NCT ID NCT07665112
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a blood test measuring the sFlt-1/PlGF ratio can help doctors decide the best time to deliver babies in women with severe early-onset preeclampsia. The trial will include 386 pregnant women between 30 and 34 weeks of gestation. Half will have delivery timing guided by the test results, while the other half will receive standard care. The goal is to reduce serious complications for both mothers and newborns.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sFlt-1/PlGF ratio blood test
- What this could lead to
- If successful, this blood test could help doctors decide the safest time to deliver in severe preeclampsia, reducing serious complications for both mother and baby.
- What could go wrong
- This is an early-stage trial with 386 participants, so results may not apply to all cases. The test may not improve outcomes as hoped, and timing decisions still carry risks.
