Specimen Collection from Pregnant Women At Increased Risk for Fetal Aneuploidy

Summary

The specimen collection is designed for the purpose of the development of a noninvasive prenatal test for T21.

Detailed 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.
