Also called Down syndrome, it is associated with moderate to severe intellectual disabilities and may also lead to digestive disease, congenital heart defects and other malformations. Trisomy 21 is the most common trisomy at the time of birth.The test looks to detect the following conditions: This occurs when there are three copies of a particular chromosome instead of the expected two.
Cell-free DNA (cfDNA) results from the natural breakdown of fetal cells (presumed to be mostly placental) and clears from the maternal system within hours of giving birth.ĭuring a pregnancy, cfDNA can be tested to give the most accurate screening approach in estimating the risk of a fetus having a common chromosome condition sometimes called a trisomy. Options are also available to screen for X and Y chromosome conditions.ĭNA from the fetus circulates in the mother’s blood. It is used screen for Down syndrome (trisomy 21) and other common chromosomal conditions (trisomies 18 and 13). Non-invasive prenatal testing (NIPT) analyses cell-free DNA circulating in a pregnant mother’s blood. It can be administered as early as 10 weeks gestation. The test can be used in singleton, twin, and egg-donor pregnancies and has been validated for use in pregnant women aged 16 to 48. It is being used in more than 100 countries around the world, and has been used to guide clinical care in over 1.4 million pregnancies.
