Primary Outcome Measures:
  • Comparison of screen positive rates between investigational testing results and conventional screening results (standard of care). [ Time Frame: 12 months ]
    The primary outcome of this study is the false positive rate of fetal aneuploidy detection for chromosome 21, 18, and 13 by the Verinata Health Prenatal Aneuploidy Test and screen positive rate for fetal trisomy (T21) and trisomy (T18) by conventional prenatal screening methods. Birth outcomes, or karyotype if available, will be used as the reference standard.

All-risk pregnant women
All-risk pregnancies undergoing conventional forms of prenatal screening


Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population is comprised of pregnant women at least 18 years of age, who meet the study eligibility criteria. Women who plan or have already completed prenatal screening for fetal aneuploidy during first and/or second trimester, will be recruited from approved participating clinical centers.

Inclusion Criteria:

  • Age 18 years or older at enrollment
  • Clinically confirmed pregnancy
  • Gestational age ≥8 weeks, 0 days
  • Planned or completed prenatal serum screening* (drawn during 1st and/or 2nd trimester)
  • Pregnancy records accessible and available for data collection (e.g., results from screening, ultrasound examinations, invasive prenatal procedures if performed, and newborn hospital discharge exam)
  • Able to provide consent for participation using language appropriate forms

Exclusion Criteria:

  • Invasive prenatal procedure (amniocentesis or CVS) performed within 2 weeks prior to enrollment
  • Prenatal screening determination by Nuchal Translucency (NT) measurement only
