Current non-invasive prenatal screening (NIPS) analyzes circulating fetal cell-free DNA (cfDNA) in maternal peripheral blood for selected aneuploidies or microdeletion/duplication syndromes. Many genetic disorders are refractory to NIPS largely because t
Noninvasive prenatal screening (NIPS) for fetal aneuploidy via cell-free DNA has been commercially available in the United States since 2011. In 2016, the American College of Medical Genetics and Genomics (ACMG) issued a position statement with specific recommendations for testing laboratories. We so...
(iii) numerous non-invasive prenatal testing (NIPT) facilities worldwide have incorporated cfDNA-based tests into their portfolio, including tests for fetal sexing and diagnosis of various fetal genomic aberrations; and (iv) a 24-marker qPCR assay has recently been developed for the detection of ...

Recent work has shown maternal CMV DNAemia to be an independent risk factor for the development of fetal CMV infection, suggesting the possibility for earlier detection10. Non-invasive prenatal testing (NIPT) via sequencing of maternal cell-free DNA (cfDNA) has revolutionized the ability to screen...
