Summary

This study aims to improve early detection of preeclampsia, a dangerous pregnancy condition. Researchers will collect blood samples from over 6,500 pregnant women between 11-14 weeks of pregnancy and compare the results with pregnancy outcomes. The goal is to see how well a new blood test can predict early and preterm preeclampsia.
