Quad Screen | Fß

The Quad Screen | Fß determines a mother’s risk for having a baby with Down Syndrome, Trisomy 18 or Open Neural Tube Defects (ONTD).

Performed between 15 weeks and 21 weeks, 6 days gestation, it is a prenatal test that uses data from biochemical markers to yield a personalized risk assessment for your patient.

The Quad Screen is a stand-alone second trimester screen that uses the same as Part 2 of the Sequential Screen | Fß, for cases where Part 1 (the First Trimester Screen | Fß) was not performed .
