Harmony screening is a non-invasive screening test for certain Chromosomal abnormalities (Downs syndrome, Edwards syndrome and Patau’s syndrome) and can be performed as early as 10 weeks gestation and up to 21 weeks 6 days.
It has a high sensitivity of detecting an anomaly (98-99%) and therefore many ladies opt to have it performed for additional reassurance.
Ladies expecting Twins may also have this test performed. Harmony screening itself is a maternal blood test, however, all ladies coming for this test will also have a scan on the day to ensure their baby is doing well and measures 10 weeks or over. Results of this test are normally available after 10-14 working days, and one of our lovely Nurses will talk you through your results.
