During pregnancy, you can have screening tests to find out whether your unborn baby has a congenital disorder or any physical abnormalities. This is called prenatal screening. There are two screening tests:

1. the prenatal screening for Down syndrome, Edwards’ syndrome and Patau’s syndrome, and
2. screening for physical abnormalities (anomaly scan).

It’s entirely up to you to decide whether or not you want to take these screening tests. This document contains further details about prenatal screening for Down syndrome, Edwards’ syndrome and Patau’s syndrome.

There is also a (printable) document about the anomaly scan.
