We are conducting a study where patient samples and information obtained from this study are intended to be used to develop a screening test in singleton pregnant people, 18 years or older, to assess the risk of developing preterm preeclampsia before they have obvious symptoms of the condition. The patient samples and information collected from this study may be used to develop future screening tests to identify patients at high risk of developing other adverse pregnancy outcomes such as gestational diabetes, preterm birth, term preeclampsia (≥ 37 weeks’ gestation), fetal growth restriction /small for gestational age birthweight, placental abruption, placenta accreta spectrum, and stillbirth.
