Testing and diagnosis
Tests to confirm Down syndrome are often done before a baby is born through amniocentesis or chorionic villus sampling (CVS).
What happens if down syndrome test is positive
For amniocentesis, a needle is inserted through the mother’s abdominal wall into the amniotic sac and a small sample of amniotic fluid is drawn out and tested in a laboratory.
If your child was not prenatally diagnosed with Down syndrome, diagnosis usually begins at birth based on your child’s physical appearance.
Doctors will ask you for a thorough family medical history, do a physical exam of your child, and analyze your child’s chromosomes. Once a diagnosis is made, additional testing may be ordered to help clinicians better understand how Down syndrome may affect your child and help spot any early complications from the disorder.
Tests may include:
- Genetic testing, in which a sample of your child’s saliva is used to identify your child’s DNA.
- Blood tests, which can help determine drug usage and effectiveness, biochemical diseases and organ function.
- X-rays, which produce images of bones.
