Active clinical trials for "Trisomy 18 Syndrome"

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.

To obtain whole blood specimens from pregnant subjects to be used for research and development and clinical validation studies of prenatal assays.

The purpose of this study is to detect whole chromosome abnormalities in maternal blood.
