NIPT stands for Non-Invasive Prenatal Testing. It is a prenatal screening test that analyzes cell-free DNA (cfDNA) from the mother's blood to assess the risk of certain chromosomal abnormalities in the fetus. NIPT is a highly accurate and safe test that has become increasingly popular in recent years. During pregnancy, a small amount of the fetus's DNA enters the mother's bloodstream. NIPT takes advantage of this by analyzing the cfDNA in the mother's blood to screen for specific chromosomal abnormalities, primarily Down syndrome (trisomy 21), trisomy 18, and trisomy 13.
