Early preeclampsia test could save thousands of newborns and moms
NCT ID NCT05521776
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a simple screening test in early pregnancy (around 11-14 weeks) can predict and help prevent preeclampsia, a dangerous condition involving high blood pressure. The trial will involve 14,500 pregnant women and aims to reduce severe complications like premature birth or low birth weight. If successful, this screening could become a routine part of prenatal care.
