Sonic Genetics provides a non-invasive prenatal test (or NIPT) called “Harmony”. This is a DNA-based blood test that measures the chance of common genetic conditions such as Down syndrome (trisomy 21), Edwards syndrome (trisomy 18) and Patau syndrome (trisomy 13).
The test requires a single blood draw, and can be done as early as 10 weeks gestation. Collecting your blood sample for NIPT poses no threat to your baby.
During your pregnancy, your healthcare providers will offer various tests to help you assess your baby’s health.
Some genetic conditions run in families. Others, like chromosomal abnormalities such as Down syndrome, typically do not. They can happen in any pregnancy.
Although the risk of Down syndrome increases with age, most babies with Down syndrome are born to women under 35 years of age. As part of your care, you will be given the option to test for chromosome abnormalities, which are genetic conditions that affect physical and mental development.
What test options are available?
There is a range of tests available to screen for and diagnose chromosomal abnormalities. Definitive diagnosis can only be achieved by examining cells from your baby collected by invasive techniques such as chorionic villus sampling (CVS) or amniocentesis. However, these procedures are now more commonly used for confirmatory testing following an abnormal result from a screening test such as the First Trimester Screen (FTS) or non-invasive prenatal test (NIPT).
Since NIPT first became available in early 2013, there have been changes to test methodologies and new evidence has emerged about test performance. We carefully reviewed the evidence regarding the accuracy and reliability of different forms of NIPT, and chose the Harmony Prenatal Test. We constantly review the medical literature on NIPT to ensure that we are providing you with a test that meets these high standards.
Performed in Australia
Sonic Genetics has performed the Harmony non-invasive prenatal test in our Australian laboratory since 2015. We have tested many thousands of women in that time.
The Harmony test is also provided by other laboratories in other countries. To date, Harmony has been performed on more than one million patient samples around the world.
