Specimen Collection From Pregnant Women at Increased Risk for Fetal Aneuploidy
Collection of Whole Blood Specimens From Pregnant Women at Increased Risk of Fetal Chromosomal Aneuploidy for Use in Development of the SEQureDx Trisomy 21 Test in the Detection of the Relative Quantity of Chromosome 21 Circulating Cell-Free DNA Extracted From Maternal Plasma

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

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.

Observational
Observational Model: Case-Only
Time Perspective: Prospective
Not Provided
Retention:   Samples With DNA
Description:

Whole blood specimens will be collected and processed to plasma. DNA will be extracted from the plasma.

Non-Probability Sample

Pregnant women between 10 and 22 weeks of gestation who are scheduled to undergo a CVS or amniocentesis procedure and will receive the fetal FISH, karyotype and/or QF-PCR results from the procedure.

  • Down Syndrome
  • Fetal Aneuploidy
