Studies* indicate that Panorama™ identifies Trisomy 21 (Down syndrome) and Trisomy 13 (Patau syndrome) with >99% sensitivity and false-positive rates of 0%, while another popular test reports sensitivities of, respectively, 79% and 50% with 5% and 0.3% false-positive rates.
Panorama™ has a >96% detection rate for Trisomy 18, with a false positive rate of <0.1%, while that same competing test has 80% sensitivity and a 0.3% false positive rate.
Panorama™ screens for Monosomy X (Turner syndrome), triploidy, fetal sex, and optional microdeletion syndromes while the other popular test does not screen for these conditions at all.
Panorama™ is the superior option.
