Outcomes
Primary outcome [1] 0 0
The RNA study is an observational trial whose primary aim is to document the performance (sensitivity and specificity) of a laboratory developed test (LDT), using fetal nucleic acid in maternal plasma to identify Down syndrome in early pregnancy.
Timepoint [1] 0 0
Within 1st and 2nd trimesters
Secondary outcome [1] 0 0
The secondary aim is to develop a sample bank to allow documentation of subsequent improvements in the existing LDT or documenting performance of new methodologies.
Timepoint [1] 0 0
Late1st and early 2nd trimesters

Eligibility
Key inclusion criteria
* Pregnant women between about 10 weeks and 21 weeks 6 days gestation who are undergoing a diagnostic procedure (i.e., chorionic villus sampling or amniocentesis) for karyotype analysis who have, on average, a high prevalence of Down syndrome (about 1:30 to 1:50).
* Three main sources are pregnancies screen positive for:

1. the combined test at 10 to 13 weeks (NT, PAPP-A and hCG)
2. the second trimester quadruple test at 15 to 18 weeks gestation
3. integrated screening (PAPP-A and the quadruple test, with or without NT).
* Variations of the integrated test such as sequential testing will also be acceptable.
* Other, less common high risk groups would be women having diagnostic testing because of maternal age of 38 years or older at delivery, pregnancies with an abnormal ultrasound highly suggestive of a chromosome abnormality (e.g., major heart defect, clenched fist), and women with an inherited form of Down syndrome (Robertsonian translocation).
