Non-Invasive Prenatal Testing (NIPT) is a blood test that is used to detect chromosomal abnormalities in a fetus. The test is performed on pregnant women over 10 weeks of gestation by taking a blood sample from the mother’s arm. The blood sample is then analyzed to search for fetal DNA that comes from the placenta.
NIPT is very accurate in detecting chromosomal abnormalities in a fetus, especially trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome). In addition, NIPT can also detect sex chromosome abnormalities in a fetus, such as Klinefelter syndrome, Turner syndrome, XXX and Jacob Syndrome. The test is a safer and more accurate alternative to invasive tests such as amniocentesis or CVS (Chorionic Villus Sampling).
