At birth, babies with Down syndrome usually have certain characteristic signs, including: flat facial features. Though the likelihood of carrying a baby with Down syndrome can be estimated by screening during pregnancy, you won’t experience any symptoms of carrying a child with Down syndrome. Are there signs of Down syndrome in pregnancy? This outcome, together with results which cannot report on sex chromosome abnormalities, occurs in 0.5-1% of pregnant women screened by Sonic Genetics. The Harmony Prenatal Test reports a result, but not for fetal sex. The Harmony test has a greater sensitivity, specificity and higher positive predictive value (PPV) than the Nuchal Translucency screening, also known as the Combined Test. The Harmony cfDNA test can be performed from 10 weeks of pregnancy, two weeks earlier than the NHS 11-14 week screening. The Harmony test analyzes cell free DNA in maternal blood and gives a strong indication of whether the baby is at high or low chance of having trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) or trisomy 13 (Patau syndrome). The superior accuracy of Harmony relies on the presence of sufficient fetal DNA in the maternal circulation for analysis. We recommend that the test be performed between 10 and 14 weeks’ gestation. But is worth knowing the standard test is still 93% accurate. While the Harmony Test is expensive, it’s claimed this method of non-invasive testing is 99% accurate.
