Down Syndrome Screening
Screening estimates the chance of Down syndrome and, depending on the test, certain other chromosome conditions.
Available approaches
Screening may combine blood testing and ultrasound measurements, or use cell-free DNA testing. Which option is appropriate depends on the stage of pregnancy and local availability.
Reading the result
A higher-chance result is not a diagnosis, and a lower-chance result cannot exclude every condition. Results should be explained in a way that helps you understand the next steps.
Your choices
Diagnostic testing may be offered after counseling. You can discuss its benefits and risks before deciding. Screening and diagnostic testing are choices, and support should be available whatever you decide.
This information supports a discussion with your doctor. Suitability, availability and any specialist referral should be confirmed with the hospital. Individual care plans and outcomes vary.
