Collection of Whole Blood Specimens from Pregnant Women At Increased Risk of Fetal Chromosomal Abnormality for Use in Development of a Noninvasive Prenatal Test in the Detection of the Relative Quantity of Chromosomal Material in Circulating Cell-Free DNA Extracted from Maternal Plasma
Sequenom, Inc.
Summary
The specimen collection is designed for the purpose of the development of a noninvasive prenatal test for T21.
Description
To collect specimens for the purpose of developing a prenatal aneuploidy test. The test will analyze circulating cell free fetal (ccff) nucleic acid from blood samples from pregnant women who have an increased risk indicator/s for fetal chromosomal aneuploidy and are undergoing invasive prenatal diagnosis by chorionic villus sampling (CVS) and/or genetic amniocentesis. The results of the ccff aneuploidy test will be compared to the chromosomal analysis obtained via CVS or genetic amniocentesis.
