Fetal Exclusion Criteria:
1. Documented record of chromosomal anomalies.
2. Identifiable structural fetal abnormalities present at time of screening or a record of such abnormalities prior to enrollment.
3. Oligohydramnios, defined as Amniotic fluid index (AFI) less than 5 cm when measured using the four-quadrant method at time of enrollment.
