Prenatal Aneuploidy Screening

Prenatal screening tests help identify pregnancies at increased risk for Down syndrome, trisomy 18, or open neural tube defects such as spina bifida. These tests have traditionally been performed in the second trimester and measure the levels of specific protein markers in maternal blood. Newer tests now combine first-trimester fetal ultrasound measurements along with measurements of biochemical markers in maternal blood to predict risk. ARUP offers second-trimester as well as first-trimester, integrated, and sequential screens.

* Sonographer providing NT measurement must be certified by NTQR (SMFM) or FMF. Please contact a genetic counselor at (800) 242-2787 x2141 prior to sending first sample to ensure acceptability.
