MatErnal BLood IS Source to Accurately Diagnose Fetal Aneuploidy

A Prospective, Multi-center Observational Study With Blinded, Nested Case:Control Analyses to Evaluate the Performance of the Verinata Health Prenatal Aneuploidy Diagnostic Test

The primary objective of this study is to determine the performance characteristics (sensitivity and specificity) of the Verinata Health Test to detect fetal Trisomy 21 (T21) compared to karyotype results obtained by amniocentesis or chorionic villus sampling (CVS).

Secondary objectives are to assess performance of the test to detect male gender (XY) and other less common aneuploidies (Trisomy 13 (T13), Trisomy 18 (T18), and Turner Syndrome (45, X)) compared to clinical fetal karyotype.

Inclusion Criteria:

• Age 18 years or older
• Clinically confirmed viable pregnancy at the time of enrollment
• Clinically determined gestational age between 8 wks, 0 days and 22 wks, 0 days
• Referred or planning to undergo CVS or amniocentesis procedure due to risk of fetal aneuploidy based on protocol-specified clinical indicators
• Able to provide consent for participation using language appropriate forms and consent process

Exclusion Criteria:

- Invasive prenatal procedure (amniocentesis or CVS) performed prior to enrollment
