The positive detection rate for cell-free DNA testing of all aneuploidies (5 for trisomy 21,2 for trisomy 18, and 1 for trisomy 13) was 100% (95% confidence interval, 99.
The underlying rate of maternal cancers that present with discordant NIPT-fetal karyotype results is unknown, but warrants consideration when multiple aneuploidies are called.
Traditional non-invasive prenatal screening for autosomal aneuploidies involves screening via a combination of ultrasound and serial detection of maternal serum markers in the first and second trimesters, with follow-up diagnosis by invasive procedures such as amniocentesis or chorionic villus sampling (CVS).
NOVP chemotherapy for Hodgkin's disease transiently induces sperm aneuploidies associated with the major clinical aneuploidy syndromes involving chromosomes X, V, 18, and 21.

CMA was equally efficacious in identifying all aneuploidies and unbalanced rearrangements that had been identified by karyotyping.
The trial found that microarray analysis, which compares a fetus's DNA with a normal (control) DNA, performed as well as karyotyping in identifying common aneuploidies (an abnormal number of chromosomes--an extra or missing chromosome causes genetic disorders such as Down syndrome and Edwards syndrome); it also identified additional abnormalities undetected by karyotyping.
