Primary Outcome Measures:
- Invasive prenatal procedures rate measure by the occurance of chorionic villus sampling (CVS) and/or amniocentesis [ Time Frame: Enrolled women will be evaluated on or before Gestational Age: Wk 28 ]
The primary objective of this study is to compare the rate of uptake of invasive prenatal procedures (chorionic villus sampling (CVS) or amniocentesis) between a prospectively enrolled cohort of pregnant women at high-risk for fetal aneuploidy who are offered noninvasive prenatal testing (NIPT; verifi® prenatal test) and a historical cohort matched for demographics and pre-test risk indications. The prospective group will include both those who accept NIPT and those who decline NIPT, but are willing to consent and complete a brief questionnaire.
