Many birth defects can be diagnosed before birth with tests. Chromosome problems such as Down syndrome can be diagnosed before birth by looking at cells in the amniotic fluid or from the placenta. Or they can be found by looking at the baby’s DNA in the mother’s blood (noninvasive prenatal screening).

Are there signs of Down syndrome in pregnancy?

Though the likelihood of carrying a baby with Down syndrome can be estimated by screening during pregnancy, you won’t experience any symptoms of carrying a child with Down syndrome.

Risk factors Some parents have a greater risk of having a baby with Down syndrome. Risk factors include: Advancing maternal age. A woman’s chances of giving birth to a child with Down syndrome increase with age because older eggs have a greater risk of improper chromosome division.

What tests are done at 10 weeks pregnant?

Non-Invasive Prenatal Testing (NIPT) screening: This cell-free fetal DNA test can be done as early as after 10 weeks of pregnancy. The test uses a blood sample to measure the relative amount of free fetal DNA in a mother’s blood. It’s thought that the test can detect 99% of all Down syndrome pregnancies.
