Comparison of blood test to results from chorionic villus sampling or amniocentesis for fetal aneuploidy detection [ Time Frame: 24 months ]
Circulating genomic material from maternal blood will be quantified using biochemical techniques to determine the presence of fetal aneuploidy. The results obtained from analysis of circulating genomic material will be compared to the karyotype results from chorionic villus sampling or amniocentesis.
