Can noninvasive prenatal testing (NIPT) be used for Trisomy 13?
Noninvasive prenatal testing (NIPT) is available for trisomy 13. NIPT is a screening option for pregnant women. This newer blood screening test has been available since 2013. Most laboratories offering this test state that the test identifies about 90% of pregnancies affected with trisomy 13. This test evaluates pieces of placental DNA that are outside of cells and are in the mother's blood. Parents are recommended not to make permanent decisions about the pregnancy solely based on NIPT results. Diagnostic testing like chorionic villus sampling (CVS) or amniocentesis can confirm or rule out a screen result. More research needs to be conducted to better understand and improve the accuracy of this test.
