Prenatal testing provides information about your baby's health before he or she is born. Testing is available to pregnant women
- Who are aged 35 or older, because they are at higher risk for having a child with a chromosomal abnormality
- Who have a family history of an inherited condition such as Duchenne muscular dystrophy
- When their ancestry or ethnic background means that they might have a higher chance of an inherited disorder such as sickle cell anemia, thalassemia or Tay-Sachs disease
- To screen for common genetic disorders such as spina bifida and Down syndrome
Two diagnostic procedures are common in prenatal testing. Amniocentesis involves testing a sample of amniotic fluid from the womb. CVS (or chorionic villus sampling) involves taking a tiny tissue sample from outside the sac where the fetus grows.
