Find clarity early

Taking the Harmony Prenatal Test is easy. It requires a simple blood draw and can be taken as early as 10 weeks into pregnancy.

Three steps to clear answers

While other commonly used tests for Down syndrome are performed later in pregnancy and require multiple office visits2, Harmony 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. Test results are reported to your provider in 7 business days or less.


Getting your test results

The Harmony Prenatal Test gives clear answers about the risk to your pregnancy of trisomies 21 (Down syndrome), 18, and 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 sex chromosomes, those results are provided as well.


Less follow-up testing

Harmony is more accurate than traditional Down syndrome blood tests.1

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