Primary Outcome Measures:
  • Sensitivity and Specificity of the test to diagnose aneuploidy in a fetus at chromosomes 13, 18, 21, X and Y. [ Time Frame: Between first trimester screening (10-14 weeks GA) and invasive testing (amniocentesis or CVS). ] [ Designated as safety issue: No ]
    The primary objective is to determine the diagnostic capability of the test to detect autosomal aneuploidy (chromosomes 13, 18, 21) and sex aneuploidy (X and Y).


Biospecimen Retention:   Samples With DNA
