The Harmony Prenatal blood Test is a new alternative test available for screening chromosomal abnormalities during pregnancy. The test uses a maternal blood sample to detect fetal cells (baby cells)which are then screened to estimate your risk of Downs syndrome (Trisomy 21) and also two other trisomy chromosomal abnormalities which affect chromosome 13 (Patau’s Syndrome) and chromosome 18 (Edwards Syndrome).

Clinical studies have shown that the Harmony Prenatal test has exceptional accuracy for assessing fetal trisomy risk. A low risk result indicates that there is a greater than 99% accuracy that the baby has none of the three trisomy conditions. A high risk result is indicative of a high risk for a trisomy condition. This means the test identifies more than 99% of babies affected with Downs syndrome (Trisomy 21), 98% of babies with Edwards syndrome (Trisomy 18) and 80% of babies with Patau’s syndrome (Trisomy 13). Testing for fetal sex is has greater than 99% accuracy.

The Harmony blood test can be undertaken any time in pregnancy after 10 weeks. The test is therefore suitable for any woman who has a viable singleton pregnancy equivalent to a gestation of 10 weeks or more. It is also suitable for the majority of Twin pregnancies.
