MD review: Your doctor will need to go ver your report in its entirety and not just just certain aspects. It sounds like you were doing first trimester screening where the 12 week sonogram measurement of the baby’s neck (nuchal fold ) would be calculated into your blood test to determine the level of risk. 1/470 is a very low risk for Trisomy 21.
