Why choose Harmony test

What is NIPT?


Non-invasive prenatal testing (NIPT) uses cell-free DNA (cfDNA) derived from the pregnancy to evaluate possible chromosomal conditions in a pregnancy. NIPT is a prenatal screening test that can be performed as early as 10 weeks of pregnancy using a single blood draw. Prenatal diagnostic tests such as amniocentesis and Chorionic Villus Sampling (CVS) diagnose the presence of chromosomal conditions. They are typically performed later in pregnancy and are associated with a small risk of pregnancy loss.
