Non-invasive prenatal testing (NIPT) is a modern technology using sequencing of free fetal (amniotic) DNA circulating in maternal blood for an accurate detection of chromosomal abnormalities in the fetus. TRISOMY test XY by means of the whole genome analysis of free foetal DNA using bioinformatic and biostatistical methods allows to identify the most common numerical deviations – trisomies of chromosomes 13 (Patau syndrome), 18 (Edwards syndrome) and 21 (Down syndrome), numerical deviations of sex chromosomes responsible for Turner syndrome, Klinefelter syndrome, XYY and XXX syndrome. The positive detection should be verified by invasive testing (e.g. amniocentesis or chorionic villus sampling).
