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...
