Comparison of noninvasive prenatal testing of cell‐free DNA in maternal blood and amniocentesis for evaluation of aneuploidy
Background: The aim of this study was to compare noninvasive prenatal testing (NIPT) of cell‐free DNA in maternal blood and amniocentesis in the diagnosis of aneuploidy. This study was designed to evaluate sensitivity, specificity, accuracy, positive predictive value and negative predictive value of NIPT for detection of aneuploidies compared gold standard test of amniocentesis. Materials and m...
متن کاملMicroarray-based cell-free DNA analysis improves noninvasive prenatal testing.
OBJECTIVE To develop a microarray-based method for noninvasive prenatal testing (NIPT) and compare it with next-generation sequencing. METHODS Maternal plasma from 878 pregnant women, including 187 trisomy cases (18 trisomy 13, 37 trisomy 18, 132 trisomy 21), was evaluated for trisomy risk. Targeted chromosomes were analyzed using Digital Analysis of Selected Regions (DANSR™) assays. DANSR pr...
متن کاملNoninvasive Prenatal Testing for Fetal Aneuploidies Using Cell-Free Fetal DNA - 5/26/17
National guidelines recommend that all pregnant women be offered screening for fetal chromosomal abnormalities, the majority of which are aneuploidies (an abnormal number of chromosomes). The trisomy syndromes are aneuploidies involving 3 copies of 1 chromosome. Trisomies 21 (T21), 18 (T18), and 13 (T13) are the most common forms of fetal aneuploidy that survive to birth. Noninvasive prenatal s...

متن کاملInitial clinical laboratory experience in noninvasive prenatal testing for fetal aneuploidy from maternal plasma DNA samples
OBJECTIVE The aim of this study is to report the experience of noninvasive prenatal DNA testing using massively parallel sequencing in an accredited clinical laboratory. METHODS Laboratory information was examined for blood samples received for testing between February and November 2012 for chromosome 21 (Chr21), Chr18, and Chr13. Monosomy X (MX) testing was available from July 2012 for cysti...
