Choosing a Prenatal Test

There are now many screening options, and it can be confusing to know which one to choose.

You can narrow your testing choices depending on how far along you are and what further testing you may consider. If you would consider having particular diagnostic testing (amniocentesis or chorionic villus sampling), you may wish to have a screening test first.

The options in italics are the ones we recommend most for your given situation, but everyone has different needs and desires. These are the options that most tend to choose in the given situation, but are not for everyone. If you choose "none," you can still have screening tests that can give you useful information.

A fetal anatomy ultrasound can be useful to find major birth defects and screen for possible chromosome conditions. This type of ultrasound between 18 and 20 weeks' gestation can give you more and different information than these screening tests, and is always an option in addition to, or instead of, these tests.
