A subject's participation will take approximately 1 hour for Visit 1. In addition, if cytogenetic results are not available and pregnancy ended in a live birth, it will take approximately 1 hour for Visit 2 (mother's postpartum checkup).
Study staff will follow subjects until data or specimens used to establish the clinical reference standard are collected, and pregnancy outcome and birth information is collected (if applicable). Follow-up can take up to 40 weeks after enrollment.
It is anticipated that sites will be enrolling subjects for approximately 4 months. Follow-up will continue for up to 40 weeks after the last subject is enrolled.
