What is the difference between a screening and a diagnostic test?

Screening tests and diagnostic tests are the two main categories of prenatal testing. Both types of testing are voluntary. Click here for a chart comparing both types of tests.

A screening test is used to estimate your risk of having a child with a certain condition. A screening test is not definitive; it gives you a personalized risk estimate. All women are eligible for screening tests, although non-invasive prenatal testing is currently only offered to women who have an increased chance of having a pregnancy with a chromosome difference. A diagnostic test is definitive and indicates whether or not your baby has a certain disease or condition. Diagnostic tests require taking a sample from the pregnancy carry a small risk of miscarriage due to procedure complications. Diagnostic tests are also available to all women, but are often offered to women who are over the age of 35, have had a previous child with a chromosomal abnormality or genetic condition, or have a positive screening result. Diagnostic tests available at our center include chorionic villus sampling (CVS) and amniocentesis.

Prenatal testing can sometimes be confusing. To learn more about first trimester screening, screening for chromosomal differences in pregnancy or options for prenatal diagnostic testing, you can watch video presentations prepared by genetic counselor Emily Hardisty, MS, CGC and Dr. William Goodnight on these topics.
