is confirmed informed health and medical decisions will follow.
Down's syndrome, or trisomy 21, is a chromosomal anomaly
leading to lower-than-normal mental ability, increased susceptibility to infections and higher incidence of leukemia, as well as to characteristic slanted eyes and skeletal abnormalities.

characterized by the presence of two X chromosomes and one Y chromosome, resulting in infertility.
The MaterniT21 PLUS test was the first commercial non-invasive prenatal test (NIPT) of its kind for the detection of a genetic chromosomal anomaly
