Harmony can be ordered for any patient as early as 10 weeks.

Patients are asking — and clinicians need to be equipped with the right knowledge. While traditional screening can miss as many as 15% of pregnancies with trisomy 21, Harmony’s DNA-based technology accurately identifies more than 99% of cases.1

The superior accuracy and low false-positive rate of Harmony compared to traditional screening tests may minimize anxiety and invasive procedures caused by false-positive results.2-4 Expecting parents will benefit from the knowledge Harmony provides and healthcare providers will appreciate the easy integration into routine protocols.

Three simple steps to accurate risk assessment:


Order Harmony as early as 10 weeks gestation. A simple blood draw is all that is required.


Send a blood sample for analysis using the Harmony kit.


Receive results within 5-7 days upon receipt of sample. Share with your patient and decide on next steps.

Note: Harmony is designed to assess risk for trisomy 21, 18, and 13 and sex chromosome aneuploidy only. It does not detect all genetic defects every problem that may occur in pregnancy.

Medical Societies Guidelines

Professional medical societies support offering aneuploidy screening, including cell-free DNA screening, to any pregnant women5-8 “

“ACMG recommends informing all pregnant women that NIPS is the most sensitive screening options for traditionally screened aneuploides…”

ACOG/SMFM Committee Opinion Number 640: “… any patient may choose cell-free DNA (cfDNA) analysis as a screening strategy for common aneuploidies regardless of her risk status…”

The Harmony Prenatal Test was developed by Ariosa Diagnostics, a CLIA-certified laboratory. As with other lab-developed tests, it has not been cleared or approved by the FDA and is not available for sale as an IVD in the US. Non-invasive prenatal testing (NIPT) based on cell-free DNA analysis is not diagnostic; results should be confirmed by diagnostic testing.
