Clinical Evaluation of the SEQureDx Trisomy Test in Low Risk Pregnancies
A Clinical Study to Evaluate the Relative Clinical Specificity Performance of the SEQureDx Trisomy Test in Pregnant Women at Low Risk for Fetal Chromosomal Aneuploidy
Pregnant women with low risk indicators for fetal chromosomal aneuploidy will be enrolled. Study blood will be collected in the first or second trimester at a scheduled prenatal screening visit, processed to plasma, and stored frozen until analysis. Each pregnancy will be followed until delivery and the birth outcome recorded.
Not Provided
Observational Model: Case-Only
Time Perspective: Prospective
Not Provided
Retention:   Samples With DNA
Whole blood specimens will be collected and processed to plasma. DNA will be extracted from the plasma.
Probability Sample
Pregnant with low risk for fetal chromosome 21 aneuploidy
  • Aneuploidy
  • Down Syndrome
  • Noninvasive Prenatal Screening
Device: SEQureDx Trisomy Test
Plasma samples obtained from maternal blood will be tested using the SEQureDx Trisomy Test, an in vitro diagnostic test that measures circulating cell-free fetal DNA. The test detects the relative quantity of chromosome 21, which is associated with trisomy 21.
