How Testing Works
The Important Role of a
Non-Invasive Prenatal Screen
If you’re pregnant, the Myriad Prequel Prenatal Screen is a noninvasive screen ordered by your healthcare provider that you take as early as 10 weeks into your pregnancy to learn about your baby’s chance of having a chromosome abnormality leading to a condition like Down Syndrome.
If you’re also interested in learning about inherited conditions you and your partner may pass onto a child, learn about our Foresight Carrier Screen here.
