Edwards Syndrome Testing

When an AFP test indicates a high risk for Trisomy 18, usually a Level 2 ultrasound (also called a targeted ultrasound) is scheduled. The level 2 ultrasound is usually performed by a perinatologist or someone else who specializes in high-risk pregnancies. They are specially trained to look for the markers of Trisomy 18. These markers, often called soft markers, are characteristics frequently seen on babies with Edwards Syndrome.
