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.
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.
Experts Support Down Syndrome Screening
Some genetic conditions run in families. Others, like Down syndrome, typically do not. They can happen in any pregnancy. Although the risk of Down syndrome increases with age, most babies with Down syndrome are born to women under 35 years of age.
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.
Fetal Sex Chromosomes
The Harmony Prenatal test can also screen for conditions caused by having an extra or missing copy of the X or Y chromosomes, including Turner and Klinefelter syndromes. You also have the option to obtain information about the sex of your baby
