cfDNA:cell free DNA,游离DNA。人外周血中不在细胞内,而在血浆中的DNA。 Streck Cell-Free DNA BCT® BLOOD COLLECTION TUBE(货号:218962和230253)是一种血浆游离cfDNA保存管。可用于NIPT样本采集。 传统的产前诊断方法是通过获取胎儿的绒毛、羊水、脐血或者胎儿的组织来进行诊断,这些侵入性的产前诊断技术对胎儿和...
A new type of prenatal screening however, offers parents-to-be a better option. Cell-Free Fetal DNA testing detects chromosomal abnormalities through a simple blood test that is more accurate than current screening tests and can be done earlier in pregnancy—as early as the 10th week, with res...
The discovery of cell-free fetal DNA circulating in the maternal blood has great potential for the development of NIPT methodologies. Such strategies have been successfully applied for the determination of the fetal rhesus status and inherited monogenic disease, but the field of fetal aneuploidy ...

Sample preparation and analysis of cell-free DNA (cfDNA) were performed as previously described (Natera Inc, Austin, TX).14 Noninvasive prenatal testing (NIPT) results indicating a risk of ≥1/100 for a trisomy were categorized as high risk and those at <1/100 as low risk. In the cases...
Obstet Gynecol Surv 2016;71(3):146-147 One of the most important technical advances in prenatal care in recent times is analysis of cell-free DNA (cfDNA) in the maternal plasma to screen for fetal aneuploidy. Use of cfDNA screening for aneuploidy was clinically introduced in 2011 in the Uni...
Dedicated to oncology, women’s health, and organ health. Natera’s cell-free DNA tests help protect health and inform more personalized decisions about care.
Plasma cell-free DNA (cfDNA) are small molecules generated through a non-random fragmentation procedure. Despite commendable translational values in cancer liquid biopsy, however, the biology of cfDNA, especially the principles of cfDNA fragmentation, re
Cell-free DNA (cfDNA) has become a comprehensive biomarker in the fields of non-invasive cancer detection and monitoring, organ transplantation, prenatal genetic testing and pathogen detection. While cfDNA samples can be obtained using a broad variety of approaches, there is an urgent need to stand...
Cell-free DNA (cfDNA) screening for normal fetal aneuploidy has been widely adopted worldwide due to its convenience, non-invasiveness, and high positive predictive rate. We retrospectively evaluated 9327 Korean women with single pregnancies who underwent a non-invasive prenatal test (NIPT) to invest...
