NCT04311749

Brief Summary

This study evaluates the utility of expanded panel non-invasive prenatal testing (NIPT) in detecting confined placental mosaicism of rare autosomal trisomies among pregnancies with placentally-mediated complications, including fetal growth restriction and severe preeclampsia.

You may not qualify if:

  • Maternal age \< 18 years
  • Multifetal gestation
  • Chronic hypertension require use of pharmacotherapy
  • Tobacco or drug use
