At birth, babies with Down syndrome usually have certain characteristic signs, including: flat facial features. small head and ears.
How soon can you tell if your baby has Down syndrome?
Diagnostic tests that can identify Down syndrome include: Chorionic villus sampling (CVS). In CVS, cells are taken from the placenta and used to analyze the fetal chromosomes. This test is typically performed in the first trimester, between 10 and 13 weeks of pregnancy.
