Placenta Clinic Audit Study


The aim of this study is to develop accurate methods to distinguish women whose pregnancies are at risk of placental insufficiency from those whose pregnancies are at low risk, by using a combination of maternal serum screening, placental ultrasound (to determine placental shape), and uterine artery Doppler in the first and second trimesters.

In addition, through blood sampling over the course of pregnancy, we will be able to evaluate potential new biomarkers and genetic molecular assays in an effort to improve our ability to screen accurately for placental insufficiency.
