Primary Outcome Measures:
  • Clinical Performance (Sensitivity/Specificity) of MaterniT21 PLUS LDT Assay [ Time Frame: Subjects contacted within 3 years after pregnancy is completed ]
    Results of the MaterniT21 PLUS LDT will be compared to the pregnancy outcome data obtained from the patient

Biospecimen Retention:   Samples With DNA
Some subjects will be asked to provide a buccal cell sample for sequencing.
