Non-Invasive Screening for Fetal Aneuploidy

Brief Title

Non-Invasive Screening for Fetal Aneuploidy

Official Title

A Prospective Clinical Study to Evaluate a Novel Non-invasive Prenatal Screening Method for Characterizing Fetal Whole Chromosome Aberrations and Other Major Defects and Deletions Found in the Maternal Blood.

Brief Summary

      The purpose of this study is to detect whole chromosome abnormalities in maternal blood.

Detailed Description

      The purpose of this study is to detect whole chromosome abnormalities on all chromosomes 13,
      16, 18, 21, X and Y, in the fetus through analysis of cell free and compound sample DNA (cf
      DNA and cs DNA, respectively) in maternal blood. In addition, major deletions and
      duplications in chromosomes 1, 4, 5, and 22 will be detected.

Study Type


Primary Outcome

Validate the prenatal aneuploidy laboratory developed test (LDT) with maternal blood samples from pregnant women who are undergoing invasive prenatal diagnosis


Down Syndrome


Maternal Blood Draw

Study Arms / Comparison Groups

 Pregnant Women
Description:  Pregnant women who are scheduled to undergo an amniocentesis or chorionic villus sampling (CVS) procedure
Intervention: Single Maternal blood draw of 20mL
