Making Decisions about Genetic Screening
Genetic testing during pregnancy can give you important information about your baby’s health. These tests can check for conditions like Down syndrome or inherited health problems. This page explains how the tests work and when you might want to talk with a genetic counselor.
What Are Genetic Tests During Pregnancy?
Genetic tests check for health problems in a baby before birth.
Some tests use:
- A blood test from you
- An ultrasound
- A sample from the placenta or fluid around the baby (only in some cases)
These tests look for problems like:
- Down syndrome
- Other problems with the baby’s chromosomes
- Health problems that run in families, such as cystic fibrosis or sickle-cell anemia
Should I Talk to a Genetic Counselor?
A genetic counselor is a health expert who talks with you about your baby’s risk for certain health problems.
You may see a genetic counselor if you:
- Want to talk about what genetic tests to do
- Are 35 or older
- Had another baby before with a genetic condition (like Down syndrome)
- Have a family history of genetic conditions (either you or your partner)
- Had a blood test or ultrasound that showed a possible problem
- Have had several miscarriages
- Are related to your partner by blood (like cousins)
- Just want to learn more about your baby’s health
The counselor will help you understand your test options and what the results may mean for your family.
