Chromosimplicity: Harmony Prenatal Test

The Harmony test assesses the risk for
chromosome conditions such as Down syndrome
and includes an optional analysis of fetal sex
and sex chromosome (X,Y) conditions.

  • Non-Invasive
  • Simple
  • Accurate
  • Affordable

Study* involving 192 total twins results demonstrated:

  • 9 of 10 affected pregnancies received a high-risk result for T21
  • 1 of 1 affected pregnancies received a high-risk result for T13
  • No false positives

Chromosimplicity: Harmony Prenatal Test

Studied in over 8,000 patients, including >2,000 average-risk women1-7

Detection Rate
False Positive Rate
(231 of 232)
(103 of 105)
8 of 10 <0.1%

X and Y analysis is >99% accurate for fetal sex. It can also assess risk for sex chromosome conditions with test performance varying by the type of condition detected.7

Demonstrated performance

Directed DNA analysis accurately detects select fetal trisomies in pregnancies of 10 weeks or more.
