Chromosomal Non-Invasive Prenatal Testing (NIPT), also known as cell-free fetal DNA testing, is a sophisticated screening test performed during pregnancy to detect certain chromosomal abnormalities in the developing fetus. Unlike invasive prenatal tests like amniocentesis or chorionic villus sampling (CVS), which carry a small risk of miscarriage, NIPT is considered a non-invasive and safe procedure for both the mother and the baby.
