Prenatal genetic tests are ultrasound exams, blood tests, and diagnostic procedures that can be done during pregnancy. These tests look for
some of the most common genetic conditions and congenital anomalies that can affect a fetus. These include trisomy 21 (Down syndrome), heart
defects, spina bifida, and others.
Most pregnancies lead to the birth of healthy babies. But about 1 in 25 babies (4%) is born with a congenital
anomaly or genetic condition. A congenital anomaly is a physical or functional defect that is present at birth. These may be changes in appearance,
function, or both.
Congenital anomalies and genetic conditions can range from mild to severe. Some parents want to know during pregnancy if their baby will be born
with one of these conditions. Finding out during pregnancy gives time to prepare for the care of a child with special needs and to investigate
additional tests or options.
The Genetic Education Modules (GEM) explain testing options for the most common genetic conditions and congenital anomalies. There are multiple
tests. Each works a little differently and gives different information.
GEM reviews testing options, the conditions that tests look for, and suggests things to think about when deciding about testing. To begin, click
