Greater clarity

Harmony Prenatal Test has unsurpassed accuracy, bringing clarity to genetic testing for common trisomies. 

Conventional prenatal screening methods using serum proteins and ultrasound have higher false-positive rates, causing healthcare providers and their patients unnecessary worry and additional invasive testing.

  • In blinded clinical trials, Harmony correctly identified over 99% of cases of trisomy 21
  • Conventional screening tests can miss 15% or more of trisomy 21 cases

Unsurpassed accuracy

  • Harmony has a less than 0.1% false-positive rate
  • This means fewer than 1 in 1000 Harmony tests yields a false-positive result
  • With conventional screening, as many as 1 in 20 women will receive a false-positive result

Harmony has one of the highest positive predictive values (PPV*) for trisomy 21 of any cell-free DNA-based trisomy 21 test.

May minimize follow-up testing

Harmony Prenatal Test helps healthcare professionals give expectant parents accurate information about the most common fetal aneuploidies. By delivering clear information about trisomies earlier in pregnancy, Harmony may minimize anxiety and follow-up invasive procedures due to false-positive results.

Any age or risk category

Harmony Prenatal Test is clinically validated for use in pregnant women, of any age or risk category, to assess the risk of fetal trisomies 21, 18 and 13.

  • Harmony is the most broadly studied cell-free DNA-based maternal blood test
  • Clinical studies in more than 22,000 women of all ages
  • Over 300,000 pregnancies tested worldwide
