Prenatal testing

As modern medicine advances, new information becomes available regarding how diseases are inherited. Now parents are given different choices to make about the health of their baby even before he or she is born. During this stage of your pregnancy, options for prenatal diagnostic testing range from noninvasive procedures, such as ultrasound and blood tests, to more invasive procedures, such as testing the amniotic fluid or sampling of placental tissues from within the uterus. Most of these tests are performed during the early second trimester of pregnancy.

Second trimester prenatal testing is available to all women, and may be recommended for those:

With a family history of a genetic disease or chromosomal abnormality
Who are over the age of 35
With a fetus with abnormalities seen on ultrasound

Parents may want to consult a specialized genetics counselor for prenatal counseling. These counselors are trained to give parents the information they need to make informed choices. Counseling also helps parents understand the effects of a disorder and ways it may be prevented or treated.

Some types of prenatal testing and procedures carry some risks to mother, baby, or both.
