Harmony Prenatal Test evaluates the risk for trisomies 21, 18, and 13 with
unsurpassed accuracy in women of any age or risk category
A Higher Standard of Care in TRISOMY TESTING
AS EARLY AS 10 WEEKS, the Harmony Prenatal Test assesses the risk of trisomy 21 with
unsurpassed accuracy in pregnant women, of any age or risk. In the first and only prospective
blinded study of its kind published in the New England Journal of Medicine, the Harmony
Prenatal Test proved superior to traditional first trimester combined screening for both
detection rate and false-positive rate.15
Harmony is Validated in
Women of All Ages 2-8, 11-13, 15
• Harmony Prenatal Test is clinically validated for use in
pregnant women, of any age or risk category, to assess
the likelihood of fetal trisomies 21, 18 and 13
• Harmony is the most broadly studied cell-free
DNA-based maternal blood test
o Blinded clinical studies in >22,000 women of all ages
o Over 400,000 pregnancies tested worldwide
Harmony Outperforms First Trimester Combined Screening (FTS*) in both Detection and
False-Positive Rate in a head to head comparison blinded study (n=15,841)

CLEAR ANSWERS TO QUESTIONS THAT MATTER
Unsurpassed ACCURACY
Harmony Prenatal Test delivers unsurpassed accuracy when compared to any other trisomy 21
blood test.
In blinded studies of over 22,000 pregnant women age 18 to 50 for trisomy 21:

This study of blinded prospective 15,841 patients compares First Trimester Combined Screening
(FTS*) with Harmony in a general pregnancy population.15
• The Harmony test accurately identified all 38 trisomy 21 cases, versus 30 out of 38 with FTS*.
• F TS* produced 5.4% (n=854) false-positives, compared to Harmony which had 0.06% (n=9) false-positives for trisomy 21

(PPV is the likelihood that a positive result is confirmed
on diagnostic testing, based on false-positive rate and
population frequency)
Harmony’s Targeted Technology
Yields Optimal Results
• Only Harmony uses a unique targeted approach to more
accurately assess the chromosomes of interest.
• Harmony’s methodology includes precise measurement
of the amount of fetal DNA and incorporates it into the risk
assessment, providing a more accurate result.

Clear Answers Early to Reduce Follow-up
The greater accuracy and low false-positive rate of Harmony
compared to traditional tests may minimize the chance
further testing would be recommended due to a falsepositive result.
Optional Fetal Sex Chromosome Assessment
• Information on sex chromosome aneuploidies can
be requested.
o Including risk for monosomy X, XXX, XXY, XYY,
and XXYY.
*Serum PAPP-A, total or free ß-hCG & Nuchal Translucency
