![]() A low-risk score means you won’t have to undergo that stressful and risky invasive testing. But for many women, it offers safety and certainty. A scan is routinely included in the price. It’s expensive: we’ve seen prices of £500 or more in the UK. Little wonder that non-invasive prenatal testing (NIPT), of which the Harmony test is one of several products, came along. 1 in 100 of them will miscarry the baby as a result of either test. High-risk patients then need to have a CVS or amniocentesis, both highly invasive tests, to confirm the diagnosis. Accompanied by a blood screen, it’s called the ‘combined test’. For a decade or more, women have been assessed for Down’s syndrome, and other fetal chromosomal problems, via the nuchal translucency scan at 12 weeks. It’s also more than 98% predictive of the risk of Edwards’ syndrome (trisomy 18) and 80% predictive of the risk of Patau’s syndrome (trisomy 13). The Harmony test is more than 99% predictive of the risk of Down’s syndrome (trisomy 21). That reading, based on cell-free genetic analysis, can give a probability score (not a diagnosis) for at least three chromosomal anomalies in the baby’s genes. It picks up a marker of the baby’s DNA in maternal blood. It can be done as early as week 10 of your pregnancy. The Harmony test, like all NIPTs, is a blood test for pregnant women. You can then decide if it’s right for you. So here are the key things you need to know about the Harmony test – and NIPT in general.
