What is the Performance of Prenatal Screening for Aneuploidy?

A new Prenatal Screening Ontario study, led by Dr. Christine M. Armour and powered by BORN data from hundreds of thousands of pregnancies, was published in the August 3 issue of Canadian Medical Association Journal.
The study evaluated the performance of Ontario’s prenatal screening system for the detection of trisomy 21 (Down syndrome) and trisomy 18, and tracked the prenatal testing choices of pregnant individuals.
This study demonstrates that pregnant Ontarians have access to a robust, high-quality prenatal screening system that reduces invasive prenatal diagnostic testing and supports informed decision making.
