During the 20-week ultrasound scan, it is possible to see fluid positioned on the back of a baby’s neck. This may indicate that the baby has Down Syndrome, however further tests need to be done, to make an accurate diagnosis.
Traditionally a woman then needed to have a nuchal translucency test. However there are some risks associated with this and these days, you have the option of a non-invasive test called the Harmony Prenatal Test. The Harmony Test doesn’t put you or your baby at risk.
