We just had our 20 week ultrasound. They noted a hypoplasic nasal bone which is typically an indicator for Down syndrome. I’ve been switched to high risk and referred to a specialist beginning next week for additional testing. My question is given the original genetic testing not showing a risk for downs what are the odds this is accurate? Should I begin preparing to give birth to a child with Down syndrome? Does anyone have any resources?
