The population impact of screening for Down syndrome: audit of 19 326 invasive diagnostic tests in England and Wales in 2008.

abstract：OBJECTIVE:Little is known about the obstetric care of an ongoing pregnancy with trisomy 21. We sought to ascertain an obstetric profile for pregnancies with Down syndrome to help guide prenatal management. METHOD:Pregnancies managed for delivery with trisomy 21 between 2003 and 2014 were analyzed. We reviewed demograp...
