What is the Harmony prenatal test?

The Harmony prenatal test is a new option in prenatal screening. Using a blood test, and a scan if clinically necessary, the risk of certain chromosomal conditions that can have a high associated incidence of miscarriage and birth disabilities or defects can be detected with high accuracy, including:

  • Down Syndrome (trisomy 21)
  • Edward Syndrome
  • Patau Syndrome (trisonomy 13)

The Harmony Test can also be used to sex the baby at no extra cost. At GCRM-BELFAST the Harmony test is carried out by Consultant Obstetrician Dr John Manderson. 

What are the benefits of the Harmony test?

The Harmony test is a new option for prenatal assessment that offers near total accuracy in the diagnosis of chromosomal conditions, such as Down Syndrome. When compared to standard nuchal testing options, the Harmony test is almost 10% more accurate in the diagnosis of Down's. Although prenatal screening tests can carry a false negative/positive ratio, the Harmony test has virtually no false/positive rate. What's more, as the Harmony test is non-invasive, it does not pose a direct risk to the foetus, which can be present in invasive testing such as in amniocentesis or chorionic villus sampling (CVS). Although the Harmony test is highly accurate in the diagnosis of several key chromosomal conditions, it does not rule out all fetal abnormalities.

Who is the Harmony test suitable for?

The Harmony test is suitable for a wide range of pregnancies. For women undergoing IVF treatment, or having a child in later life, a prenatal test that offers near 100% accuracy in the diagnosis of congential conditions can provide great relief. The Harmony test is suitable for:

  • All singleton pregnancies including IVF pregnancies
  • Twins if conceived naturally
  • Twins by IVF if using patient's own eggs

The Harmony test can also be used to sex your baby, this part of the test is suitable for:

  • Singleton pregnancies only (not twins)
  • All IVF singleton pregnancies regardless of whether the egg is provided by a donor or patient
