Non-invasive prenatal testing (NIPT) has the potential to screen for a wider range of genetic conditions than is currently possible at an early stage of pregnancy and with minimal risks. As such, there have been calls to apply a ‘threshold of seriousness’ to limit the scope of conditions ...
Noninvasive Prenatal Testing (NIPT) || The Role of Cell-Free DNA-Based Prenatal Testing in Twin Pregnancydoi:10.1016/B978-0-12-814189-2.00006-2Mackie, Fiona L.
Testing with NIPT can be done as early as 9 to 10 weeks of pregnancy, up until the time of birth. It is more accurate than other forms of prenatal screening, with a sensitivity ranging from 90 to 99% and specificity ranging from 99 to 100% depending on the condition [4]. When com...
根据Fetal diagnosis and therapy上的文献的报道,判断孕胎儿的周数的重要指标是crown rump length 检称CRL--- 即头臀长或者胚芽大小, 妊娠49~56天的中位数是大于10mm的,所以当检测的要求是妊娠周数大于7周时,宝宝的头臀长需要大于10mm去接受检测才是对受测者最大的保障。 胚胎长度(CRL)与妊娠早期天数(GA), ...

Karyotype techniques were performed using standard procedures either on amniotic fluid (AF) cell culture during pregnancy or on placental tissue obtained after delivery. Centromeric probes were used for interphase FISH techniques. Uniparental disomy (UPD) was tested using methyl PCR after sodium bisulfite...
