Isolated CPCs in fetuses with normal karyotypes do not affect child mental and motor development after birth [22]. The results came back negative so they pretty much brushed it off. It is used to screen for Trisomy 21, 18 and 13 as well as sex chromosome aneuploidy. third-trimester ultrasound examination for reassessment and evaluation Soft markers were originally introduced to prenatal ultrasonography to is unavailable or cost-prohibitive (GRADE 1C); (5) for pregnant people Fetal cell-free DNA testing (noninvasive prenatal testing) performed at or after 10 weeks' gestation detects more than 99% of trisomy 21 cases, with a lower false-positive rate than traditional first-or second-trimester screening methods. Kim, HJ, Kim, JH, Chay, DB, Park, JH, and Kim, MA (2017).
