A new, DNA-based technology

When you are pregnant, your blood contains fragments of your 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 certain other genetic conditions.

Other commonly used tests for Down syndrome are performed later in pregnancy and may require multiple office visits.

A more accurate test 

The Harmony Prenatal Test is a screening test that is more accurate than traditional Down syndrome blood tests.1 The Harmony test is much less likely to give a false-positive result compared to traditional tests such as the first trimester screening test.That means there will be much less chance your doctor would recommend follow-up diagnostic testing, such as amniocentesis.2

Harmony also tests for two other genetic conditions, trisomy 18 (Edward syndrome) and trisomy 13 (Patau syndrome).

In addition, with Harmony you have the option to evaluate fetal sex, X and Y sex chromosomes.

Non-invasive prenatal testing based on cell-free DNA analysis is not considered diagnostic. Once you have your Harmony test results, you can discuss your pregnancy care with your healthcare provider.
