For Expecting Parents

Three steps to clear answers

While other commonly used tests for Down syndrome are performed later in pregnancy and require multiple office visits2, Harmony test delivers clear answers as early as the first trimester with a single blood draw.

  1. A maternal blood sample is taken at week ten of pregnancy, or later
  2. DNA in the sample is analyzed using proprietary Harmony technology
  3. In most cases, the test results are reported to your provider in 7 business days or less

Receiving your test results

The Harmony Prenatal Test gives clear answers to questions about the chance for your baby to have trisomies 21 (Down syndrome), 18 or 13.

Once the analysis is completed, your provider receives the results and shares them with you.

If you also selected analysis of fetal sex, X and Y chromosomes,  and 22q11.2 deletion, those results are provided as well.

Reduce the need for additional testing

The Harmony Prenatal Test is more accurate than traditional screening tests for Down syndrome.1

With the Harmony test, there is less chance your doctor will recommend follow-up diagnostic testing, such as amniocentesis, due to a false positive result.
