NIPT screening & Nuchal Translucency - Complimentary rather than alternatives

The advent of the Non Invasive Prenatal Test has been a major advance for the detection of Trisomy 21 (Down s.), Trisomy 18 (Edwards s.) & Trisomy 13 (Patau s.) and reduces the need for invasive tests which have up to a 3% risk of miscarriage. There has been a subsequent tendency to abandon the previous nuchal translucency ultrasound and biochemical test because of the increased accuracy of detection of the trisomies with the NIPT test which can detect 99% of Down syndrome fetuses ...

Potential Fetal Anomalies

However this is not the case: for example it has been noted that up to 50% of congenital heart malformations are missed (RADIUS Study) in this way. Another example of this was a Dutch study of over 5,000 patients scanned between 16 and 24 weeks. Those skilled sonologists and sonographers   missed 10 m...
