Study summary

The overall significance of this study is to develop a laboratory developed test (LDT) to use a new marker in the maternal blood to better identify pregnancies that have a child with a chromosome abnormality such as Down syndrome (trisomy 21), Edward's syndrome (trisomy 18), Patau syndrome (trisomy 13), Klinefelter syndrome, (47, XXY), and other chromosome abnormalities. Accomplishing that task would reduce the need for invasive amniocentesis and CVS procedures.

Study population

The investigators anticipate enrolling 1000 subjects who are presenting for prenatal diagnosis by CVS or genetic amniocentesis for increased risk for fetal aneuploidy.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • This study is only applicable to women who are between 8 and 30 weeks' gestation and who have been determined increased risk for fetal aneuploidy. In the interest of expediting and simplifying this study, the investigators want only women who have already decided to undergo second-trimester amniocentesis or CVS.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2009, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
