The First Trimester Screen | Fß^SM

A Simple Safe Non-Invasive Test

The First Trimester Screen | Fß^SM reliably assesses a mother’s risk for having a baby with Down syndrome, Trisomy 18 and Trisomy 13 in the first trimester of pregnancy.

Performed between 9 weeks, 0 days and 13 weeks, 6 days of pregnancy, the First Trimester Screen | Fß^SM is a prenatal test that uses data from a blood test (biochemical) and an ultrasound examination (biophysical) to yield a risk assessment that your physician will present to you.

Y Chromosome Assessment

With an additional whole blood sample, Y chromosome assessment is an option available to patients who are pregnant with one baby that will assess the fetal sex. The presence of a Y chromosome is predictive of a male baby, while the absence of the Y chromosome typically means the baby is female. The result of this added evaluation will further refine your risk analyses for Down syndrome, Trisomy 18, and Trisomy 13.
