Clinical significance

See NINA3 (without fetal sex detection and sex chromosome abnormalities) version for general test information Detecting sex chromosome abnormalities: - In singleton pregnancies, sex chromosome aneuploidies can also be detected. Sex chromosome aneuploidies detected include 45,X, 47,XXX, 47,XXY, 47,XYY. - Fetal sex classification concordance : 100% XX ,100% XY ,90.5% XO, 100% XXX ,100% XXY , 91.7% XYY - In twin pregnancies, the presence or absence of Y is detected but sex chromosome aneuploidies cannot be detected. Performance in Twin Pregnancies: - Trisomy 21: Sensitivity 96,4%; Specifity 99,9% - Trisomy 18: Sensitivity 95,7%; Specifity >99,9% - Trisomy 13: Sensitivity 93,6%; Specifity >99,9% - Présence of Y: Sensitivity >99,9%; Specifity >99,9%Due to even lower prevalence, data for higher-order pregnancies (triplets or higher) were insufficient to establish appropriate statistical models to estimate accuracy of aneuploidy detection.
