Can 4d ultrasound detect Down syndrome?

Ultrasound scans aren’t a full-proof way of testing for Down syndrome in babies. They can detect some indications of potential markers that are commonly seen in Down Syndrome babies but can’t give a definitive answer. A Detailed Anomaly Scan done at 20 weeks can only detect 50% of Down Syndrome cases.

At what age are you considered advanced maternal age?
