Brief summary
The PREPPeD study proposes that predelivery placenta-derived maternal circulating biomarkers reflect placental health, capacity and ageing, and can help predict onset and complications of delivery both in complicated pregnancies as well as in clinically uncomplicated term/post-term pregnancies.
Detailed description
The main aim of the PREPPeD study is to explore whether placental health, evaluated by maternal blood biomarkers in late pregnancy, correlates with delivery outcomes in both healthy and complicated pregnancies.
