Can nipt detect turner syndrome? Noninvasive prenatal testing (NIPT) detects variant of Turner syndrome not detectable by fluorescent in situ hybridization. J Matern Fetal Neonatal Med.
How accuracy is NIPT test for Turner syndrome? NIPT can also be used to detect other fetal genetic diseases, such as fetal sex chromosome aneuploidy (7). In our study, the total positive predictive value (PPV) of NIPT was 54.54%, which was 29.41% for Turner syndrome, 77.78% for 47,XXY, and 100% for 47,XXX and 47,XYY (7).
How accurate is genetic testing for Turner syndrome? Certain features of Turner syndrome limit the accuracy of the test and have to be announced with the patient or the couple before testing. The DR is 95,8% for an FPR of 0,14 %,13 but the the positive predictive value (PPV) is as low as 9 % in some studies14 and much lower as, for example, for Down syndrome.
Can Turner syndrome be detected prenatally? Turner syndrome may be suspected by prenatal cell-free DNA screening or certain features may be detected on prenatal ultrasound screening. Prenatal diagnostic testing can confirm the diagnosis.
