Non-Invasive Prenatal Testing (NIPT) is currently the most effective and safest screening method to detect congenital defects caused by chromosomal abnormalities.
By analyzing the cell-free fetal DNA present in the mother's blood from the 9th week of pregnancy, NIPT provides an accurate diagnostic result of over 99% for Down, Edwards, and Patau syndromes.
