Harmony Prenatal Testing

What is the Harmony Prenatal Test?

When you’re pregnant, your blood contains fragments of your baby’s DNA. Harmony Prenatal Test is a new type of screening test that analyses this DNA in a sample of your 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.

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.
