SCREENING OF CELL-FREE FOETAL DNA

The Harmony Test, carried out in collaboration with the Toma Laboratory of Busto Arsizio, is a non-invasive prenatal screening performed on foetal DNA circulating in the maternal blood (cfDNA).
This test is used for the diagnosis of major chromosomal disorders, and it is carried out right after an informative consultation and an ultrasound evaluation.
The test is based on the most recent developments of non-invasive prenatal tests and has shown a high detection rate (99%) in diagnosis trisomy 21 (Down Syndrome) as well as identifying the 98% of foetuses with trisomy 18 (Edwards Syndrome) and 80% of foetuses with trisomy 13 (Patau Syndrome); with a false-positive rate from 0.06% to 0.01%.
