Harmony Prenatal Test

1.How accurate is the Harmony Prenatal Test?

Harmony’s DNA-based technology correctly identifies Down syndrome in more than 99% of cases. By comparison, traditional
blood tests can miss as many as 15% of Down syndrome cases in pregnant women.
Harmony 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, such as amniocentesis.

2. How does the Harmony test work?

When you are pregnant, your blood contains fragments of your developing baby’s DNA. Harmony Prenatal Test is a new type of
test that analyzes DNA in a sample of your blood to predict the risk of Down syndrome (trisomy 21) and other genetic conditions
called trisomy 18 and trisomy 13.

3. How is the Harmony test different from other blood tests for Down syndrome?

Harmony delivers clear answers as early as the first trimester with a single blood draw. Other commonly used 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%.
Harmony uses a unique method of targeted DNA analysis that, combined with extensive quality controls, achieves over 99%
accuracy and a false-positive rate less than 0.1%.

4. Can the Harmony test also evaluate the X and Y sex chromosomes?

Yes, Harmony Prenatal Test includes the option to evaluate the number of X and Y sex chromosomes, if you ask your doctor to
request this additional analysis.
Should I take the Harmony test if I am under 35?
The risk of Down syndrome in a pregnancy increases with maternal age, however, most cases occur in women who are under age
35. Harmony, a new type of DNA-based blood test, has been extensively validated in women both over and under 35.

5. When can I take the Harmony test?

You can get the Harmony test with a simple blood draw as early as 10 weeks into your pregnancy, or any time later in pregnancy.

6. How long does the Harmony test take?

Harmony is a simple blood test, so it only takes a couple of minutes at your healthcare provider’s office.
In seven to ten working days, your healthcare provider will receive the results and can share them with you.

7. I’m expecting twins. Can I get the Harmony Prenatal Test?

Yes. Harmony can be used in twin pregnancies.

8. I’m expecting a baby through IVF. Can I get the Harmony test?
