What is the Harmony Prenatal Test?

Harmony Prenatal Test is a new type of screening test that analyses this DNA in a sample of blood to assess the risk of Down syndrome (trisomy 21) and two other genetic conditions, trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome).

For Women of Any Age or Risk Category

Traditional blood tests can miss as many as 20% of Down syndrome cases in pregnant women.
The Harmony Prenatal Test was developed to be a more accurate prenatal Down syndrome screening test for women of any age or risk category. It is a DNA-based blood test that has been extensively tested in both the under 35 and over 35 age groups, studies have included pregnant women ages 18-48 for trisomy 21.

A More Accurate Test

Harmony has been shown in clinical testing to identify greater than 99% of Down syndrome cases and to have a false-positive rate of less than 0.1%.

Clarity Early

Harmony Prenatal Test requires a single blood draw and can be done as early as 10 weeks or later in pregnancy.

Results are usually available in about seven business days. Other commonly used screening tests for
Down syndrome are performed later in pregnancy and may require multiple office visits.

Minimises Need for Follow-up Tests

The greater accuracy and low false-positive rate of Harmony compared to traditional tests may minimise the chance that further testing would be recommended due to a false-positive result. Follow-up testing might include an invasive procedure, such as amniocentesis.
