Harmony fits any practice

Harmony fits any practice

Harmony Prenatal Test gives general obstetricians and specialists alike the flexibility they need to use Harmony seamlessly with other prenatal procedures, including ultrasound. 


Three steps to accurate trisomy screening

  1. Order Harmony Prenatal Test as early as 10 weeks
  2. Send a blood sample for analysis using the Harmony specimen and transportation box
  3. Receive results as soon as 3 days and most within 5 days after sample receipt




The SUPERIOR ACCURACY and low false-positive rate of Harmony compared to traditional screening tests may minimize anxiety and invasive procedures caused by false-positive results.1-3

Integrating Harmony Prenatal Test into existing workflow

After confirmation of pregnancy, Harmony can be performed as early as 10 weeks gestation or later in pregnancy. Harmony can be performed with or without nuchal translucency (NT) ultrasound. Patient education needs are similar to those for other routine trisomy screening tests.
