Using a DNA-based technology, the Harmony prenatal test has been shown to identify more than 99% of pregnancies with Down syndrome.1 By comparison, traditional blood tests can miss as many as 15% of pregnancies with Down syndrome.2
The Harmony prenatal test is also much less likely than traditional tests to give you a false-positive result, meaning there is much less chance your doctor would recommend follow-up invasive testing like amniocentesis.
The Harmony prenatal test is a screening test. Results should be confirmed with diagnostic testing such as amniocentesis and chorionic villus sampling (CVS).
When you are pregnant, your blood contains pieces of DNA from your developing baby. The Harmony prenatal test is a test that analyzes DNA in a sample of your blood to assess the chance of Down syndrome (trisomy 21) and other chromosome conditions called trisomy 18 and trisomy 13.
The Harmony prenatal test delivers clear answers as early as the first trimester with a single blood draw. Other screening tests for Down syndrome are performed later in pregnancy and require multiple office visits. Traditional 1st trimester serum screening tests are associated with a false-positive rate as high as 5%.2
The Harmony prenatal test uses a unique method of targeted DNA analysis that, combined with extensive quality controls, achieves over 99% detection rate and a false-positive rate less than 0.1%.1
Yes, the Harmony prenatal test has the option to evaluate sex chromosome aneuploidy (monosomy X, XXX, XXY, XYY and XXYY) and 22q11.2 microdeletion
Yes. Recent professional society guidelines support the offering of non-invasive prenatal testing to the general population. 1-2 The Harmony prenatal test has been extensively validated in women both over and under 35. 3 Most babies with Down syndrome are born to women who are less than 35 years old, even though the chance for Down syndrome in a pregnancy increases with a woman’s age. 4
As early as 10 weeks into your pregnancy, you can take the Harmony prenatal test with a simple blood draw.
In seven days or less, your healthcare provider will receive the results and can share them with you.
Yes. Harmony prental test can be used in twin pregnancies for trisomies 21, 18 and 13. Sex chromosome aneuploidy and 22q11.2 microdeletion cannot be tested for in twin pregnancies.
Yes. In most cases, the Harmony prenatal test can be used in pregnancies conceived through in vitro fertilization (IVF).
For questions that relate to your specific case and personal concerns, it’s best to talk to your healthcare provider. A list of Questions for your healthcare provider you can print for your next visit is available.
The Harmony Prenatal Test is a non-invasive prenatal test (NIPT) based on cell-free DNA analysis and is considered a prenatal screening test, not a diagnostic test. Harmony does not screen for potential chromosomal or genetic conditions other than those expressly identified here. All women should discuss their results with their healthcare provider, who can recommend confirmatory, diagnostic testing where appropriate. The Harmony Prenatal Test was developed, and its performance characteristics determined by Ariosa Diagnostics, Inc., a CLIA-certified and CAP-accredited clinical laboratory in San Jose, CA USA. This testing service has not been cleared or approved by the US FDA.
